Thanks for the tips. I tried using a puller to force the bolt through, but that was a no go so ended up just cutting the bolts and removing the entire leaf pack. I'll take it to a spring shop nearby on monday and have them press out the old bushings. There probably is a simper way but I was struggling and hate making no progress. Oh well, the end result will be worth it. Thanks again!
