I used 5/8"-long pan head Phillips sheet metal screws on the sides up front. I don't know how to specifically describe sheet metal screws. For the three screws in the "glove bin" I used M5-0.8x12 countersunk Phillips screws. All the screw heads were spray painted flat black. The heads of the M5 screws I used are a smaller maximum diameter than are the countersink holes in the bin so perhaps the OEM screws have a special head to make them flush with the bin floor. My 1972 FSM (Section 123) shows holes for the front screws (for "floor finishers" from Aug '71 it says) but no screws are shown in the drawing. The rear three screws are likewise nowhere to be seen.

Any clue of the 3 to 5 screws type and lenght for the center console of a 1972 240z?

Here's something to read through. This guy is something else, he don't know half arse hence the name Hardway.

My daily driver.

No doubt, the camera and video have been my best friends through this journey. Once I get under there if it looks like swapping the old ones out are going to require a lift i may just wait and get someone to do it for me.

What you see on my car is what the body/paint shop came up with when they mixed the Glasurit paint to the stock 901 Datsun code. I left the inside of the right tool door the original paint. The original paint is a touch darker/greyer to my eye. Garrett

I have used an epoxy product from Caswell to coat a tank. It's very thick and would deal with pinholes pretty well. I suspect that tank will have quite a few pinholes once it's properly cleaned. It might be hard to do in an apartment setting...

Yes, for the hand throttle

I remember the vendor, 'Auto World', from back in the 1960's (I still have their 1965 catalog sitting on my book shelf). I didn't realize that they were still in business. The website pays some homage to the original operation, but doesn't make it clear whether there's a historical link between 'then' and 'now'... "Oscar Koveleski founded Auto World in the basement of his home in Scranton, Pennsylvania in 1958. The small mail order hobby business grew to great proportions and became known for its annual product catalogs, which were filled with every car-related item an adolescent hobbyist might desire." The current iteration of Auto World is based in South Bend, Indiana.

I just used the link that Zkars provided in his #2 post. The Gyraline website currently features their Black Friday deal and offers the option of having the price displayed in the currency of the customer's location. IIRC, I had to select the 'G1' (iPhone) or 'G2' (android) product first, add it to my Cart, and then go to the Cart to see the price. I tried this posing first as a Canadian customer, and then as a American customer. The quoted price in Cdn $ for a Canadian customer was significantly higher (numerically) than that for an American customer -- but maybe that was purely the result of performing a currency conversion. Additional costs for shipping/handling and duties/tariffs might get tacked onto the Canadian price afterwards and not become visible until later in the check-out process. A quick internet search indicates that Gyraline was incorporated in Delaware in March 2024, with operations based in California and Texas. I have no idea where they do their manufacturing. Given the the nature of the design and the relatively low production volumes, it could be as simple as contracting out to a US-based additive manufacturing company ('additive manufacturing' = commercial-grade 3D printing).

@siteunseen THANK YOU! This is the kind of info I was looking for. Much obliged.

My 12/70 has the flapper. And I'm REALLY late to the party! I just picked up an air cleaner housing that only has one hose barb coming out of it (I'm assuming it is for the valve cover breather hose?), has the filter retainer ring on the inside of the filter and there is no sticker, but has sticker residue on the top. What sticker would have been there, and what production dates of cars would have come with this style of box? Jan. - July '70 cars?

What I have...the red/blue are flat head, the blue/clear are philips, and the black/clear are torx. This seems to be the standard from what I've seen in stores for decades. Maybe some older tools were different.

On the hunt for an automatic transmission shift bezel in brown. I'm hoping someone made the switch from auto to manual and has one on a shelf somewhere in good shape. Thanks!

Known for their wonderful Northern California events, the MMT is especially exciting because it is held in our backyard near the Santa Cruz Mountains. We love attending BCR events. They are always well-organized and the variety of cars is tremendous. http://www.zcarblog.com/wp-content/uploads/2025/11/MMT_2025-01-scaled.webp http://www.zcarblog.com/wp-content/uploads/2025/11/20251108_084405.jpg Our client Jim H attended the MMT rally with his 1971 Datsun 240z. It is now sporting a Rebello 3.2L with Jenvey ITB EFI, Recaro Specialist seats, CD009a 6-speed transmission, our Z Car Garage Big-Brakes and Z Car Garage CV Axles! http://www.zcarblog.com/wp-content/uploads/2025/11/20251019_072243.jpg http://www.zcarblog.com/wp-content/uploads/2025/11/20251019_072149.jpghttp://www.zcarblog.com/wp-content/uploads/2025/11/Screen-Shot-2025-11-20-at-5.02.36-PM.png Jim had a great time driving on the event and kindly shared these photos.

Installing KYB Struts with KYB dust cover and bump stop. I noticed a fairly significant gap between the housing tube and the bellow. I thought it needed to be sealed to the housing. Is that true? Opinions welcome.

And, as I noted in 2023, that NAPA kit seems to be NLA. But do your own checks. You might just get lucky and find one sitting on some NAPA shop's shelves. I just re-checked my old files. The NAPA kit (PN 6601000) was described as a 'RANCO HTR-100' rebuild kit. It was evidently applicable to the heaters used in the Studebaker Avanti, so it's conceivable that it was used across the entire Studebaker line (Lark, Hawk, etc). A little snooping around a Studebaker owners club website might turn up a lead. RANCO appears to have been swallowed up by Robertshaw. Most of the focus for the RANCO product line these days appears to be in electronic temperature controllers used for commercial/industrial heating systems. I suspect that the 'RANCO' of 2025 may be nothing more than a brand name (i.e. it's unlikely you'll find a RANCO factory with a parts desk). Just one thing, though: I see that NAPA Canada lists something called a 'URO Parts Heater Valve Repair Kit'. A little checking indicates that URO Parts is a brand marketed by A.P.A. Industries (Simi Valley, CA). A.P.A. provides aftermarket parts (incl. cooling system parts) for a variety of European, Asian and North American cars and trucks. In their website, they say: "A.P.A. specializes in accurate reproduction parts for classic vehicles, including a wide variety of items that are no longer available from the dealer". Maybe there might be some leads there. The heater control valve design used in the 510 and Z probably wasn't unique to Nissan. In fact, the Nissan heater design bears certain resemblances to the British 'Smiths' unit that was used in so many UK cars back in the 1950's and 60's. A little investigation along these lines might turn up a British shop that specializes in heater restorations and has a back room filled with obscure parts like a little rubber washer that will fit your 510's control valve.

A friend of mine has a smoke machine, good for finding air and vacuum leaks, if my intake gasket is not leaking, I'm not going to touch it. Jim

Could the braided hoss that goes to the brake booster have a leak? How do you check for leaks? Carb cleaner?

The next thing to attack is the firewalls . I can’t finish the passenger upper frame because I need access to spot weld the firewall panel . The firewall is sandwiched between the inner fender wall and outer . I also have an issue with the passenger side firewall panel from KF . The drivers side worked out pretty sweet and I should be able to do a decent job welding it in . The biggest obstacle is that I wanted to preserve the vin# that’s stamped on the wall so I had to cut around it . The passenger side doesn’t line up right as you can see but the pics . They said they will send me a new one . I think the panel wasn’t square on their stamping machine . KF has been really good supporting their products . I’ll also add that their drivers firewall panel does not include the doubler for the inside

This was solved today by retarding time! Thanks

It's been a whole year since the surgery! Can hardly believe it, time flies when you're on the better end of healing. Thanks for all the prayers and well wishes, they worked. Next is a mid-foot fusion that I'm dreading but the docs said after a year with the knee replacement they could do it. I had planned a day of relaxing in the driver's seat of the 240 but it has rained like a cow pissing on a flat rock. Maybe tomorrow?
