Paul,
If the rubber insulator is the only part destroyed (like mine was) and the metal hanger parts are good, drill out the rivets and remove the insulator. I then went to NAPA and found the longest rubber insulated exhaust hanger they had in stock. I believe it was for a Dodge diesel P/U. Bent the rubber in half, got some stainless bolts, hi-temp black paint for the metal. Looks factory.
