Shims

[cayce_brunswick-]

My truck was wrecked sometime throughout its life. It’s had a hood, fender and door replaced. It has welded in rockers and not a straight line or gap anyplace. I’m going to try and fix that this winter. I ordered cab mounts and I plan to start with the bed being centered on frame, then center the cab on frame and to the bed, work forward. I need some help! I need shims, probably fender shims and probably shims for cab mounts and core mounts. Does anyone have any info on a good supplier? Also any advice anyone has, I would love to have. Last, my hood sits really high in the back. I can physically push it back down when the hood is closed but hate doing that every time. Is that a sign of wore out springs? Any any info on that?
