guys I just picked up new Boge rear shocks for my SIX. Is it a special spring perch or will anyone work? Thanks in advance. Been 30 years since I restored my last car so it is a lot learning to get back in the swing. Jim

not sure about 6. but ones that i pulled off my 4 had built in bottom spring perch. one fixed position.

Boge was the OE supplier.
Pics would help.
But pretty certain the stock deep stamped lower perch will do the trick.
BUT..... they have no height adjustment.

The perch is unique to Boge rear shocks. The three bumps on the shock body won't support other removable perches.
I've made a substitute before, I think using a cut off lower perch from a KYB. Maybe I can find a picture.

@jim dorociak

Pretty sure i have a pair of those perches if you need them. They are soecial to Boge
