Whichever one is closer. You can try rolling it on the ground but if don't have the original steelies with the windows all around your gonna have to jack it up and pull the tire off. Then get a straight steel something, l think I used a crow bar, wedge it in between the wheel studs the lugs go on and try to turn it to line up. It's a pain if they're stuck nice and tight. Probably be best to put the lugnuts on so as to not bugger up the threads. I'm using my phone so I can't help as well with pics like with my laptop. I can in the morning if you hadn't done it yet. Sorry. And I hope you can figure out what I'm trying to get across. Saturday is beer and football. LOL

I was considering a master vac leak, pumped on brakes, pedal went to floor, resivor for rear brakes was dry, filled up, fluid going somewhere. Rebuilt cylinder, now other issues. Should put that on hold and get back to vac leak problem.

I can't remember on the gasket, swapped carbs years ago. Going down another rabbit hole now with brake problems. Can we still get the gasket?

Ok, cancel the Yarbinator. I found a video on YouTube and it only takes three wires. Frankly, the video is one of the best produced car vids I’ve ever seen on YT. If I knew how to link it…

Mine has 2 of those holes - does it matter which I use?

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?

Had to resort to the old drum puller once. Came off with a very loud bang. Putting on a couple of lug nuts loosely prevents it from exploding into your lap

Was that an accident or wanting them off? BFH love!

Oh, and I don't see anything else glaringly wrong in the pic, but was wondering... When the flat top to round top conversion was done, did they (you?) use a new intake/exhaust manifold gasket, or reuse the old one?

Well let's hope fixing those two plugs helps your running issue. If the two 10mm head bolts were screwed in somewhat tight, they probably sealed "mostly". If those bolts are the only vacuum leak you found, they probably weren't large leaks.

I didn’t make the larger pieces of upper frame rail. Same car I bought my roof from I also bought all his straight scrap pieces . It was enough of a challenge to make that 1” filler strip between the pieces he sent me - ha . I don’t have the tools to do that complex of bends and curves. The tool is just a right angle air grinder with a Roloc sanding discs . I use that tool more than most . I have cut- off wheel mandrel and scotch bright disc options . I actually have 3 of them with different mandrels on each .

There was a post around that had someone replacing the guts of the old module with the new HEI but I cant find it. I might do that, but mount the box on the firewall or something. I like that it would appear more period correct. @EuroDat did that to his '77

That should be it in the red circle. I saw my OE aluminums the other day cleaning up my storage building and they still have the rubber plugs in them.

Wait i thought the cog was accessed through the hole on the front of the drum?

I really thought the access was through the backing plate that the brake pads are attached to. Seems like there's a rubber oblong plug that you pull for access to the cog wheel to back the pads off.

As I'm working on a 260z engine, I found somebody decided to plug some holes in the balance tube by using two 10mm straight thread cap screws (bolts). The original holes were tapered but they forced metric cap screws into the holes, ruining the threads. Notice they were only able to get the screws in part way. I've attach a photo, I circled the two locations. Without drilling the holes out I was able to thread the holes with a 1/8-27 tapered pipe tap, thus allowing me to use 1/8" plugs. All other plugs I've found seem to be the proper threads. Jim

Yes, I understand how they are designed, I just wanna use them how I wanna use them! LOL I really wouldn't like the look even if the heads DID bottom out, still kinda klunky looking. The BSPP plugs on the other hand (they have a lower profile head), look pretty good, but they won't bottom out in the tapered holes.....so I guess I could tap the holes to a parallel thread and use thread sealant. I think you are right though, once I get all the holes I need to plug measured, I will order the allen screw type.

Lol!! The Yarbinator. Love it! ☺️

Tapered pipe threads are supposed to tighten up on the threads, not the underside of the head. In fact, if the head were to bottom out, the threads would run the risk of not being tight enough to seal. In other words... The hex headed plugs you have there are working exactly like they should. You would stand a better chance of achieving your "clean look" with the recessed hex head "Allen screw" type plugs.

Little more poking around today. I ended up just ordering a HEI module specific heat sink off amazon. I had considered just finding some sheet metal or aluminum, but I didnt have anything laying around and a small chunk from the hardware store was almost as much as the heatsink itself. I think its going to end up on the other side of the strut tower. There is a nice empty space there I can utilize. I don't really want it there, but for the sake of simplicity, thats where I am going to put it. There was a post around that had someone replacing the guts of the old module with the new HEI but I cant find it. I might do that, but mount the box on the firewall or something. I like that it would appear more period correct. I started looking more closely at the fuel system, pretty much all the rubber is dry rotted and unusable. Same with the vacuum lines, so I ended up ordering a bunch of hose and Ill just replace all of it. Im not sure about the hard lines yet. I jacked up and crawled under the car and drained the fuel tank. It was pretty much empty but the stuff that was in there was.......nasty. The fuel was incredibly dark and full of debris. I know there is a place in town where I can get the tank reconditioned, so I'll look into that. While I was under there, I took some pics of the undercarriage. I dont think its too bad. It was a New Mexico car after all.

OK, here we go..... The threads on the balance tube all seem to be BSPT (1/8" and 1/4") The threads on my intake manifold where the water lines used to go are still a mystery. I have a feeling they are just a metric thread (not pipe thread), so I will have to do more investigating when I have an assortment of metric bolts to try. Also, my thermostat housing is at my storage, so I cannot check those outlets right now, either. I guess everything is a process......stay tuned! Here's my new dilemma; The pipe plugs I ordered from McMaster for sizing purposes are external hex head, and they do not thread deep enough into the balance tube for the head to bottom out and seat on the flat of the balance tube. Not the clean look I was going for. I think I'll try the internal hex drive (like a regular socket set screw) plugs and hope they sit flush or a little recessed when seated. If I don't get a good, clean look that I like, I may have to weld the holes up and grind them smooth. Oh, the lengths we'll go to for these cars!!!! LOL

Sounds good - I'll give it a shot. Thanks

If the light is right you can probably see the notches through the hole. In practice you just jam a small screwdriver in the hole until you feel it grabbing the notches of the adjusting wheel, Keep jabbing to get the wheel to move. It's kind of tedious, you don't get much movement per unit of effort.

Mine actually has 2 holes on it which is weird since all of the drums I've seen online only have 1. So I just spin the drum until the hole is near the wheel cylinder then use a small screwdriver to turn the shoes in?
