OK, I broke done and bought a set of Cal Tracs Traction bar set up from 
Calvert Racing. Someone on the group said they were great. I talked 
with them before I ordered and told them it was for my 73 Gremlin and 
that the stock rear end was being replaced with a Ford 9", (3" dia.
 
housing). They said that part # 1020 (Jav/AMX)was the one I needed. 
Wellllll,,, They came today and it was obvious that the shock mounts 
were not going to work as they were too close to the rear end housing 
and angled the wrong way. After talking with them it was decided to 
send back their spring plates/mounts and also send them my original 
plate/mount and they will design a new mount to make sure it fits 
GREMLINS with the staggered shocks and 3" dia. housing. Otherwise I was 
impressed and have already installed the forward spring mount set-up. 
They said that I should have the "NEW" design mounts within 10 days.
