Darby,
Stop by a good spring shop..the one I go to rebuilds or makes springs...not just installs them. They will have bins full of pins, bushings, shackles etc.
Hang onto the lock nuts...those are hard to get.
The main spring bolts are a replaceable. As far as getting the bushings out, I mashed mine out with a hammer. I left the old eye bolt in the bushing and it came out. I used the same eye bolt to knock new ones back in. Crude...but I don't have access to a press. They came out without too much work and I did not hurt me or the truck.
