240z's don't really have much in the way of crush zones anyway, thin bumpers, light sheet metal, thin doors, lap belts, etc. The later cars got better but they are not modern multi air bag cars. Some risk comes with the territory. Sort of like riding a motorcycle, you just have to drive defensively. The likelihood that the tubing comes straight into the passenger compartment is fairly low. Personally I am glad my local government doesn't micromanage me. I'm a big boy and can make tough choices all on my own. That is not intended to be insulting to anyone here, I just don't need a bureaucrat parent...the two I had are gone now, God bless them, and I'm not shopping for replacements

and then I get humbled Now admittedly I have some excuse. I was multi tasking on multiple cars and projects. Then I took a big swig of beer, which happened to have a wasp in it. Stung me in the throat, the little monster! Had to hurl him back up. When the swelling started to get spooky, ended up at Urgent Care getting shots in my rump. Spent the rest of the day asleep in my recliner. So the plating didn't turn out. I will strip them and try again on Saturday maybe

The adblockers kill the revenue to the site though. If you are going to ad block you should just pony up and be a supporting member to offset it IMO...

Interesting! I will look

You are correct the dimensions are much better. Some of that may be because I can use some pressure when measuring as opposed to the way I was measuring. The distance piece is stamped "B". I am assuming it is original. The distance piece from the first side was also a "B" piece. I don't know what these pieces are made out of but they are very hard and dense and tend not to rust.

Very creative! yeah, I can't imagine it takes much to torque the front end around on one of these cars

Ok. So I received a package today and headed down to the shop. The bearings seats all look good except for a little overspray Initially I measured in the scalloped areas. That allowed me to back up against two points and set the heel of the caliper against both sides of the opposing scallop Distance piece @Captain Obvious I have another question, how firmly do you hold the caliper? I can easily move the needle 0.005" with finger pressure. I have also found you have to swing the caliper back and forth looking for the smallest dimension to be sure you are square to the bore... Off of these dimensions, it would appear the bearings are being crushed by roughly 0.007" That seems like a lot of the bearings don't have any slop...?

I thought this would be my first choice. After I verify I can measure with the CO specialty tool...

Good progress. Keep at it...

Fabulous. I hope you are mulling a solution for me if my measurements prove correct...there's beer in it...

By the way, that's a nice looking little shed!

Yeah, I was a little incredulous at this thought I might be able to later. all these parts are masked up in the paint booth currently. That would be great! It would remove one of my variables I agree this is what I thought was going on. I was pretty careful when I set the bearings to make sure they were down on the seats. I wonder how thick that little washer is? Maybe I lost it when I pressed it apart...

Those are all good tips. It is also nice that these cars are relatively speaking, easy to pull because the sheet metal is so light so there are no really high stress loads to speak of

45's are a lot of carb for a 2.4L engine, most people run 40's

That looks like lots of camber up front...

The cam looks good, nice and shiny!

I have found the embedded search engine is subpar to using google, unfortunately

One of the threads I read last night. The guy was a helicopter crash firefighter on a navy ship. They told him if the magnesium wheels on the chopper catch fire you can't extinguish them because they burn so hot it breaks the water into hydrogen and oxygen. He also said they burn so hot they'll burn through the ship deck in just a few minutes. So the SOP was to push the burning chopper overboard...

My hub specs out at larger than even an A hub! So it can't have been wallered? out. The dimensions would be smaller in that case. Confusing... Now it is possible my measuring is suspect. I would only have to be off by 0.010" to be a B hub, at least on the one side

@grannyknot

So I mic'd the second "B" piece @ 2.068" . The seat to seat dimension I got was 2.087" & 2.080" I measured in the scallops using the "B" piece as a surface to work from. Didn't have a sacrificial set of calipers So do the bearings have 0.020" freeplay? @Captain Obvious If I can't sort the other hub and have to disassemble it I will measure those parts too

Was it grannyknot or Sweatybetty that found something as a substitue for this?

Yea, I thought it was odd to be standard. As for the hub. I intentionally only did one hub at a time so I couldn't mix up parts and I had one to check against if I forgot something. The first one that seems like it will be too tight had the small copper washer in it. The second did not appear to have it. I never saw it and don't believe I lost it. I put the copper washer under the inside flange for the hub, between it and the bearing face. When I ran the nut down with the impact wrench it got too tight to turn. Now it's possible that it was over torqued but I seriously doubt it because my impact isn't really that strong. With it off the car I figured I would be challenged to get it torqued any way. So I figured I would need to have it on the car so I could use a wheel to hold it still to torque. Speaking of that, how did you torque Mathews hub? My torque wrench doesn't read that high. I also thought I should probably try to mic it so I know what I have...

I did some research on welding magnesium wheels last night. Evidently they can be tigged but it can be a difficult process and they are prone to stress cracks, that have to be found and repaired. A wheel like the one pictured earlier with out the lip is probably not good for anything but a hose reel like Gav said

If you try to die them it will have to be to a smaller size. If it were mine I would try to remove the stud and then get new studs from an automotive supply house or someplace like Fastenal. The studs are nice and make the work easier. But you have to be careful you don't snap them off, because they will have to be drilled out if you do. If you want to try to get them out put two nuts on one of them and tighten them against each other. Then put a wrench on one of the nuts and try to turn the stud out. It appears you are missing the rubber cover that goes around the clutch arm to prevent things from dropping in at the clutch.
