I thought it was Olds, but it looks wider at the front? we were pondering this for the wife’s 55 and we stumbled on this pic. Thanks
55 pontiac star chief, this is the wider version where it runs up the door. the std chieftan used a narrower piece of trim
Now your getting greedy asking two questions. I imagine getting nice pieces are going to take time but maybe try one of those large Pontiac sites , Hemmings etc. One avenue you could go down is having them painted on. I have seen some nice paint work where you have to do a double take .
