adjustable rear upper control arms. which year do i need?
I put a 71 buick 8.5 in my 67 gto a few years back. Need to correct my pinion angle ,and wondered if it mattered if I used the early arms {longer } or the later arms {shorter}.
I would think the longer arm shortened would be better as long as there is enough adjustment. haven't decided a brand at this point. Experiences or opinions? thanks Tim |

You will need the 64-67 arms. The ears on the housing are in the same place, you need the control arms for the chassis used.
I would look at either BMR or UMI.

I like the Spohn Del Spheres with two rubber bushings in the rear end.
