I got my leaf springs off the truck ready to clean em up and paint. I got new spring eye pins, bushings, shackles, U-bolts, everything needed for installation. I also got new rebound clips to replace the old ones. They're about 1" wide x 1/4" u-shaped brackets used to clamp (3) leaf springs together at the ends of the leaf springs. They're held together on the leaf spring with a rivot in the center of each bracket and a bolt with a sleeve that goes through each leg of the bracket. To take the olds off, I had to cut off the heads of each rivot. The rest of the rivot stems are still in the leaf springs. How do I go about getting the rest of the rivot out. I don't want to us heat, fear of weakening the spring. I thought about leaving the remaining existing rivot stem there and attaching the new bracket to the hole in the new bracket then welding the rivot stem to the new bracket. I do have new rivots that were supplied with the brackets, but I'm afraid taking the old rivots out will damage the leaf spring to the point I can't install the new rivots.

Any suggestions?

Thanks,
