I bought the bushing kit from advance auto (Part No.
K80085) and installed last Saturday. Each kit comes with 4 thermoplastic bushing (2 top 2 bottom), one bolt, nut, and washer for lower end connection to sway bar.
The top bolt mounted for the frame was reused the kit also included a metal bushing for the top. This was a straight forward installation soaking both top and bottom blots with PB blaster before loosening is recomended.
You will need a 6 inch extension for top bolts on both sides, to work aroung fuel lines on L, and muffler pipe on right.
This simple installation really made a difference in the ride comfort, prior to replacing the bushings the rear was loose.
