Just to add to the Qa1 i used them o anumber of car chevy ford etc. but when it came to the mopars i came across a problem.

THe front were fine.

THe rear however were off the bushing that fits in the shock crossmember was too small and mover back and forth on the bolt . i had to add alot of spacer to make it work and i didn't like it.

I called Qa1 and of course they were unaware of the problem this shock in question fit both a 73 cuda and a 69 road runner. I had 2 sets same problem on both. Hopefully they fixed this problem.
