you can rebend them with a propane torch, heat 'em up, clamp 'em down, and get out the sledge, just be careful, real careful, or go to your local spring shop, gotta be a few in hotlanta, then ask em for a couple new sets of spring clamps, they make a few different models, my shop had 4-5 different kinds, just make sure you get the kind that need to be tight, otherwise they will slip out again. Another option is to have a shop run a bead on em, so they don't move and then use a table vise to crank em tight again....
off the top of the head. (no, i didn't make em up, I've seen all these before.) probably a few other options out there... good luck.
