  1. I am in the process of installing the bucket’s interior. Often times I find that parts need to installed, removed, adjusted/repaired and then re-installed. A while back I bought plastic rivets for interior. Two sizes are required. The taillight panel requires 8. I believe they are $3.00 each. The interior plastic requires approximately 40. These are larger and come in bags of 10 at approximately $7.00 a bag. I don’t think that they are available at your local hardware store so there is shipping cost and worst of all for me time delay. So, the cost of these plastic rivets is annoyingly expensive (approximately $50+) considering it is just a fastener. These rivets are neat but in my opinion there are a few issues. To remove one you poke the plastic inset pin through the rivet. In a blind situation the pin goes into the bowels of the chassis never to be found. Without the center pin the rivet is useless so it is a throw away. Some suggest using a nail, or a cotter pin or something else. If I did, I would have a bunch of these alternatives rusting away and clinking and clattering away somewhere within the bucket. A bit of this is tongue in cheek – but mostly not. The second issue is that these plastic rivets cannot be tightened. Oddly enough on some of the plastic panels one of the fasteners is an actual 4mm screw. I think they did this because – they could. The material the panel was being attached to was thick enough to accept threads. Where the plastic panels attach to the remainder of the body the material is too thin to accept a thread so they used the plastic rivet. In addition to the single use aspect of the plastic rivet the panels wind up becoming loose or squeaking especially after 40+ years. I recently stumbled across a post discussing “internal rivets”. ZCARS (forum member) offered an alternative called a Riv-Nut. I was not aware of this device, but became intrigued with the solution. I suppose most of you have experience with this, so this might be a bit boring, but for the uninitiated I hope this will help you in the future. I am a novice when it comes to the use of this device or the install process. These are my opinions and experiences, and should not be considered the end all. If there are errors – they are not intentional and I would appreciate your corrections/improvements. Riv-Nut goes by a number of other names: Rivet nut, nutsert, blind nut. It is installed in a fashion similar to a common rivet. It’s purpose is to provide a means of creating the equivalent of threads for a screw in thin metal, and it additionally works when you cannot get behind the material, for example in the middle of a panel where there is no access to the backside. I could have used this countless times in the past. Often times this problem is solved with a nut that is tac welded to the back of the material. This does not work well for the DIYer. Many have no experience or equipment to weld, sometimes you cant get to the back of an area, and in some cases the material does not accommodate a welding solution. Of course, I have used sheet metal screws in the past. I hate screwing anything with a point on it into a blind area, and sheet metal screws do not like to be unscrewed and refastened many times. There is a fastener I don’t recall its name but you slide it over the edge of a hole. It creates the equivalent of a thread to hold a sheet metal screw. I have even used something similar with a captured nut embedded for a screw. This however only works at an edge. The Riv-nut is, in my opinion, an elegant solution – Thank you ZCARS. Here is a photo of a plastic rivet (on the left, and riv-nuts on the right #3, #10 Above image you can see the threads inside the riv-nut .How it works - The tool has a main body with some sort of handle or arms to apply pressure. There is a part called a mandrel which attaches to the tool. The mandrel is specific to the size of the Riv-Nut involved. The size of the hole is not the same size as the bolt or screw to be installed. Install the mandrel on the main body of the tool. The end of the mandrel that is exposed is threaded. Inside the riv-nut are threads. You screw the riv-nut onto the mandrel. Next you put the riv-nut through the material (just like a common rivet). While holding the riv-nut in place in the hole you apply pressure by squeezing the handle. Different tools have different handles. To provide more leverage, necessary for larger bolts, some tools have longer arms and require two handed operation. Other tools look like a common rivet gun and operate using a single hand. At much higher cost there are air powered versions, some attach to a drill others use just a mandrel and two wrenches. All of them have some sort of mechanism that applies pressure to the mandrel threaded end and withdraws the mandrel from the material which causes outward force, which then collapses the outer part of the riv-nut trapping the material. Obviously the portion of the riv-nut that collapses cannot be associated with the threads in the riv-nut. If you look at the outside of the riv-nut there is a collar which rests against the outside of the material that you are attaching to the riv-nut. There is a knurled portion of the riv-nut next to the collar. The threads of the riv-nut begin where the knurled portion stops. The knurled area is the part of the riv-nut that collapses against the blindside (backside) of the material. You then unscrew the mandrel from the riv-nut. There is a bit of technique involved which is gained through experience. You don’t snap the riv-nut like a common rivet. Recall that the tool is threaded on to the riv-nut. You need those threads in tact. If the riv-nut snaps it is because one of two things has happened. Either the threads on the riv-nut have given way or the threads on the mandrel have given way. So, you only want to collapse the riv-nut enough to grab the material surrounding it. Now there are different types of riv-nuts: aluminum and steel for example. Using a 3mm mandrel is a fairly delicate operation. I used aluminum riv-nuts. I thought that I would rather have the riv-nut break rather than the mandrel. Also, since I was only attaching light plastic panels the amount of holding force required was minimal. The main difference between aluminum and steel riv-nuts is holding force. So, the material of the riv-nut and the size of the riv-nut affect the holding power. When a riv-nut is destroyed during installation you need to remove it by drilling it out. When an aluminum riv-nut fails you can see the remnants of the threads on the mandrel. They need to be removed. There are a number of very good videos and printed descriptions that will do a far better job of describing the process then this post, but I thought this might get you interested enough to consider this solution. There are a number of different tools to install riv-nuts. They come in different sizes and shapes and of course at a range of price points, from $15 to many hundreds of dollars. My research led me to buy an astro-pneumatic 1442. It costs around $90. It has many very good reviews. It will accommodate a number of different size fasteners including metric (#5- #8) and a number of SAE screw sizes. I believe this is a great long term choice for me. Having said that Astro-Pneumatic does not offer a #3 or a #4 mandrel. I called Astro and they confirmed that they do not offer smaller mandrels. Most of the holes involved for these plastic panels are 5mm (diameter). This requires a 3mm riv-nut. Turns out most of the more robust tools do not offer a 3mm option. You could drill the holes to accept a larger diameter fastener, I wanted to leave myself the option of going back to plastic rivets if necessary so I decided to invest in a second tool. The 1442 requires two hands. It is medium size 13 inch handles. The handles open wide to give you more leverage. Some of the places that you will want to install a 3mm riv-nut require a tool with a smaller profile. A smaller tool will cost between $15-$30 approximately. In fact if you are using aluminum riv-nuts that are small, then a small profile, inexpensive tool might be the smart choice. Now here is an interesting data point. It turns out that #3 and #4 mandrels that are part of some less expensive sets actually fit the astro 1442. I actually bought a cheaper kit and used its mandrels on the astro 1442. So, in retrospect I would still buy the astro 1442 – it works very well, and it appears to be quite robust. I think it handles small and large riv-nuts in aluminum or steel very well. I would then enhance its capability by purchasing a #3 and a #4 mandrel. The smaller, one handed tool, is not a necessity, but I think it will help in tight places. I think it will probably have a shorter lifespan, but I do not think that it will be utilized as often as the astro. 13 inch Astro 1442 (Left), RZX 8 inch (Right) both are in their closed position Above: Astro 1442 and RZX in Open position #3 mandrel (left), #8 mandrel (right) Update 8/31/20 So it has only been a short while but I have installed a number of RiV-Nuts. Most of them were 3mm and the remainder were 4mm. All were Aluminum. I can not comment on the performance of these tools using steel rivets. I was very impressed with the performance of BOTH tools ( the Astro-Pneumatic 1442 ANd the RZX. The RZX single handed tool worked much better than I exppected it would. Some of the nut-serts have to be installed in the hatch area with the tool facing the sky. Using a 2 handed tool would have been impossible there just isn't enough room, but the RZX performed excellently. With the 1442 and a 3mm nut-sert some experience is required to know har far to close the handles. Too much pressure and you snap the aluminum insert. The RZX reliably worked when closing the hand grip all the way. As I said I have no experience with the RZX and steel Riv-Nuts, but I believe both tools are good additions to my tool set.
  2. Hi ladies and gents. I'm restoring an early 01/70 240z here... looking to restore the original finish on some of the parts and fasteners, etc. Since it's close to a "paint" related question, i'm posting it here, but feel free to move it if incorrectly categorized! The photos I have of the tear down are not detailed enough. I'm looking for some of the following things: brake lines and brake line bracket coatings (cad, yellow zinc, silver, dark green?)rear brake drums coatings (black, natural finish, clear coat?)rear differential coatings (all black? black housing, aluminum coloured cover plate with clear?)hood latch and door striker coatings (cad, yellow zinc, silver???)essentially, i'm looking to find, or refinish the items I have in their original finishthe car is essentially a shell, restored to original paint color, very well done. and now all the parts are on the floor and I've got to sort through them and refinish what needs refinishing and send out what can't be done here. is this the right place to post this? if not, can someone please steer me in the right direction? if there are any historians that have access to some photos of certain items, I would love to speak to them, and compensate them for their time. Thank you!
  3. I'm just rifling through the 9 million bolts here with the 01/70 resto project. I found a bag of these bolts, brand new (top right: 08120-8501E) that sandwhich the trans halves together. The ones I have pulled from the trans, and also some of the ones that I have discovered in the box-o-bolts have a head marking that says TR on one edge of the hex, and 7 on the opposite edge of the hex, and the washer is slightly thicker than the new ones. On the new one, it has the italicized "7" that I have come to expect on many of the datsun bolts, as I've seen 7's and 9's embossed on the hex heads on most Nis/Dats. Now I know I'm splitting hairs here, but I have new bolts, so I might as well use them... But did the TR 7 marking ever show up on any datsun bolts? Is this an early Datsun thing? I would much rather use what came on the car, to be honest, since I'm getting them tumbled and replated at some point. They are the exact same thread and length.
