I can relate a story my buddy and i had regarding an AAR Cuda we bought from a friend.

This was early 70s after the AAR caught fire and he sold it to us.

We re did the car and ordered a set of Hookers to race with.
Well we couldn't get them to clear the chassis or some other parts, (been a long time).

Called Hooker with the problem and they finally asked us if our Cuda was an AAR.

Said their experience was that the driveline geometry was one-of-a-kind for center of gravity improvement
for the AAR races.

Sent us a re-worked set that worked.

I've heard others say this was not the case.....but that was our experience.

Edit, OOPS, I now realize this was probably about a RB six pack, so disregard if not pertinent
