Rear Spring Retainers and Hardware Updates

[Frederick H.]

I've gone through several of the threads regarding the issues with retainers and would like to know if anyone has updated recommendations/preferences for which vendor(s) to use for ordering new rear suspension parts (especially the retainers) that will be as correct as possible (Zip, Corvette Central, etc.). Although I haven't used it yet, a big thanks to Gary B. for loaning out his swagging tool to the members for the retainers.

Thanks in Advance,
Fred

Fred, the last time I brought the cups I got from Long Island corvette( sure miss them). I would think Zip corvette has the correct shallow cups, and were natural no plating . If you can find some NOS rubber bushings I would buy them. But rubber bushings are available from most venders.hardware kits are around also. But if you have originals I would re-use. A quick note on the trailing arm through bolt are a one year only(63). No cotton pin to lock the nut, it uses a Flat washer, lock washer and hex nut.

Ed, I just checked part numbers in the AIM against bolts and cushions on eBay and the AIM does show use of a cotter pin for the castle nuts at the end of the bolts. Also, original GM numbers the guy has on eBay do not match the AIM #'s so they are probably for a later year? eBay #'s 458982 for the bolts, 3831586 for the cushions. I also found some "new" cushions that I purchased from LI some time ago.

Thanks,
Fred

# in eBay for the cushions is correct, AIM # for the bolts is 3831585.

Fred, I believe if you have a very late 63 it may have cotter pin and castle nut. My 10xxx had no castle nut and no cotter pin.

My Mar car is 2nd week, so should be the same.
