Back from the grave ...

Can you elaborate more please regarding to following topic

AP2 - beefier mount and narrower distance between 2 arms

AP1

hard to tell by picture

The ap2 still has bump steer, the bump steer kit on your ap1 would probably be the best option.

Sorry to bring this back from the dead almost five months later, but can anyone measure the difference in size between the mount points on the ap1 vs. ap2 RUCA. Bought a supposed ap2 subfram and RUCA but not 100% it is in fact ap2 and would rather like to know before I take my car apart to compare. Could not find any info on any solid differences between the two.Also how would they fit on the ap2 subframe.
