Barke Question E to A

OK - have an entire disc brake setup from a 70 E body, will these work on my 71 A body?

............yes, u may need A body disc upper control arms[73 up]........kim..........

OK, so if I had 73 greater upper control arms this would work? What about 68 B Body uppers for Disc brakes, will those control upper arms work

Nope -they gotta be 73-up UCAs with the large ball joint.

Thanks -

If you dont want to replace your upper control arms you can get an adapter for the small ball joint from DrDiff.

You don't want the '70 E-body spindles or rotors. 70-72 e body spindles have a different dimension on the inner wheel bearing, and originally used 2 piece rotors. They repop them now as 1 piece finally, but they still cost more than the '73 up rotors. Last I checked Autozone had them for around $80 per rotor. Not horrible, but the '73 up stuff is cheaper and you have more options (drilled/slotted/etc.) I think someone is making bearing spacers for these now, but I'd just find a '73 up set. Or use a set of F/M/J body spindles, they're easy enough to find in the wrecking yards.

Calipers and brackets should also be the pin type on the E-body stuff. Not a huge deal, just different from stock A body stuff.

As far as the UCA's, you'll need '73 up A body UCA's or the adaptors from Dr. Diff. None of the others will interchange.
