Anybody out there in SYC land have a set of GM 12 bolt spring perches that they wouldn't mind parting with? Thanks!

Thanks for the reply Mark - somebody modified the actual perches on this rear - good used ones will also work if anybody has some.

Thanks Jerry - the re-pro ones aren't quite correct. I'll check with GM tomorrow (didn't even consider that they may still be on the shelf). Anyone who is willing to part with a set of nice used - please PM or email me.

FWIW, I had a BE rear that had the perches modified. The guy I bought it from had the repo perches installed and when I got the rear it was determined that the perches were not put on correctly. The perches are to have a slight angle to them so the leaf springs will fit properly when installed to the frame. This is very key, and of course they need to be :clocked: properly as well.

Long story short, the rear was brought to Moser in Indiana, and they replaced the perches, ensured proper alignment, installed new bearing and made everything right. Great service!!

Thanks for the info Eddie - my original perches are not cut all the way off - just modified. So I have the proper orientation still in place (hopefully). I've got a RH perch coming - still need LH - anybody? I'll take a set if need be. NOS or good used is OK.

I believe 2 degrees angled "in" at the front of each perch.
I am sure someone can confirm.
