The side trim on my 67 cutlass supreme convert. has been removed.
Also the hood center strip and the rear peice. What would such pieces be valued at in good condition?

 

A complete set that's nice would likely run several hundred dollars. Does your car still have the mounting holes for the clips? If not, you'd have to locate those and drill them out again. I've got a 1964 Cutlass convertible project car that the previous owner removed the trim and welded all those holes up. I decided to just live with most of the trim being gone, which isn't factory but does look cleaner. John
