Need some help re suspension..

There are two sets of bushings in the rear. The bushing where the shackle bolt goes through the spring is two pieces. An 8 piece set will do the rear of the springs. I've only found the front bushing as an each. NAPA et. al. have these as rubber bushings. PST or Just Suspension will have these in poly??? as well.

I recommend you try to find a couple of factory LCA with the sway bar tabs. It lets you use the factory bar on the front which reduces the chance of bar to caliper contact. The factory mounts seem to be sturdier than those that use the lower shock bolt. That's my 2ยข worth.
