Help with rear leaf spring bushings

I used poly on my car from PST, but on one of the other cars I used a Moog rubber with the steel shell.
Boy that was fun getting those in.:D
The poly's are easy since they don't use a steel shell.
Thats good to know about the polys. I just spent 16 hours replacing my uca bushings...wonder if poly would have been the way to go there as well.
