My brothers is a little beat and he would rather buy new than try to straighten. This piece is about 77" long x 3" high.

I have seen some later trim that is thinner reproduced but that is not what he is looking for.

...

The Firechicken piece is totally different. Nobody is doing the 67 rocker trim, and probably never will. I have sold about a dozen of them over the years, but the supply is drying up.

We were thinking about buying a b-body piece and cutting it down. There is no real choice about having it there as he left the holes.
I would try to straighten it myself, but it has two holes in it that I know I can't fix. Maybe see if Mike at All-trim can do it, but don't know if he is taking new work or not (or if my brother has the cubic dollars).

How well does the 68-69 piece work if the holes are already there?

The 68-69 piece is reproduced by Metro Molded Products but I am not sure if it will cover all the holes. When I get back home I will check and see if I have any 67 pieces left.
