At the Spring Fling in Van Nuys, CA there used to be a vendor that specialized in restoring grills. I think they are in the LA area. Does anyone recall the name of the company?
As post#3 said "King of Trim" I have them do multiple items from grille repair and restoration to dash bezel, heater control panel & glove box door for my 1972 Plymouth Scamp. They are great!
