I'm doing both sides of course. I just trying to figure out the best course of action before I start. I don't want to drive around with the broken bolt and I can't leave my car at work or in my friend's shop, which are the two places I have enough tools for this sort of operation.
This all started because I was experiencing some rear hop, and I figured an alignment should help. Right now my plan is to replace both bolts and bushings and get it aligned, then do the whole rear suspension next summer once I get the funds. I'm also getting sick of rust so I may take a wire bush to most of these parts while I'm at it and put rustoleum or bedliner on them.
