Here are the parts you will need including reinforcements and stiffeners (from 440 racer) to repair frame damage. You will need to get about 50 stainless 3/16 nc(#10) X 3/4 bolts, lock nuts and flat washers. About 25 steel 3/16 pop rivets. A tube of Loctite 272 will help hold all screws from moving. The OEM stuff is fastened with Avis aluminum rivets so screws are the best replacement, Another good practice is to apply a bead of epoxy resin to all joints and pop rivets before assembly
