75 GP belt line moldings

Anyone know of anyone who makes reproductions of the factory type with the rubber outside lip? How difficult are these to replace? Any information is greatly appreciated.

Any updates? 73-77 GP is difficult to find off the shelf headers that fit without a lot of hammer modifications. Even the cheap 3 tube headers require some hammer work.

I also believe the 557 blocks were produced from mid 1975-1978 including the 1977 W72. The only non 557 blocks built after 1975 were the 1978-79 W72.
