You can get belts from any of the suppliers.. I like Ground-Up Restorations or Heaartbeat City. Bolts are available also. I don't know if the plastic covers that cover the bolts (at the floor as well as the roof) are available. If you want lables they are available from Snakeoyl products. They wont sew them on repo belts though. The repo belts are very close to stock,there is something different with the weave pattern. I couldn't notice it though.
Good Luck
