obrut Posted January 11, 2023 Report Share Posted January 11, 2023 I'm starting to assemble my front suspension on my 72 510. I bought the car and it was partially disassembled. Are the inner washers thicker and stepped or is it just a washer? Outer just a washer? I'm running stock arms with stock moog bushings. Quote Link to comment

datzenmike Posted January 11, 2023 Report Share Posted January 11, 2023 They are both specifically called 'special washer' but what makes them special I don't know. Must be important. Probably thick as they support the outside of the two bushings. The one closest the front between the cross member and the LCA is 54537-A0800, the one to the rear is 54538-U0101 if that helps.

If they are just washers I'll measure and find some but some of the pictures I see it looks like a spacer or maybe two washers stacked together. Edited January 11, 2023 by obrut Quote Link to comment
datzenmike Posted January 11, 2023 Report Share Posted January 11, 2023 The holes have to fit that pin sticking out of the cross member but the front most one is stopped by a widening, can't be large enough to slip past this point. Quote Link to comment
thisismatt Posted January 12, 2023 Report Share Posted January 12, 2023 If I recall correctly, the washers on the control arm side are stepped and serrated to grip the inside race of the control arm bushing, and I think the inside one has a special taper on the inside for the bolt. I don't think the washer on the opposite (front) end is anything particularly special. The bolt is very special, with a tapered shoulder on the control arm end that wedges into the tapered hole through the crossmember, locking it in place and giving it additional strength at the sheer point.

KELMO Posted January 12, 2023 Report Share Posted January 12, 2023 The one closest to the cross member is stepped. The one at the end of the pin has a "notch" in it. I will look around later today. I think I may be able to get you some pics. Quote Link to comment
obrut Posted January 12, 2023 Author Report Share Posted January 12, 2023 (edited) This is what I have When I bought the car the arms were held on with bungees so the car could roll. Looks like I need the special inner washer, then slide control arm on then a washer with a notch and nylock nut. If anyone has these special washers let me know, I'm going to put a post in the wanted section. Edited January 12, 2023 by obrut Quote Link to comment
Stoffregen Motorsports Posted January 12, 2023 Report Share Posted January 12, 2023 You don't need a nyloc. A regular nut will tighten down against the sleeve of the bushing. Use a lock washer though. On second thought, maybe the original nut is a nyloc... Quote Link to comment
thisismatt Posted January 12, 2023 Report Share Posted January 12, 2023 The originals are nylocs 2 Quote Link to comment
Icehouse Posted January 13, 2023 Report Share Posted January 13, 2023 I might have a pair of those washers if you need them. Quote Link to comment

I sent Jeff a message, hopefully he has the washers, I think I should be able to buy new nylocs after i figure out what thread size they are. I'll post some pictures of the washers when I get some so if someone else searches for pics in the future. Quote Link to comment
Stoffregen Motorsports Posted January 13, 2023 Report Share Posted January 13, 2023 Is it a 12x1.5? Or 10x1.5? Man, I used to know this shit. 1 Quote Link to comment

Stoffregen Motorsports Posted January 13, 2023 Report Share Posted January 13, 2023 That's what I recall. Maybe 10mm on the front and 12mm on the back. I don't remember it being a fine thread though. So 1.5 maybe? Quote Link to comment
KELMO Posted January 14, 2023 Report Share Posted January 14, 2023 (edited) Posted this pic in your ad. I can get diameter and thread pitch from the pin tomorrow if needed. Edited January 14, 2023 by KELMO Edit: provided I can remove that stinkin' nut. 1 1 Quote Link to comment
