I have the same problem with trying to get the spare tire well fixed on a 68 coronet wagon.
I was on the bubble as to which color to paint it because the Brady bunch brown just doesn't cut it. Problem is that 67/ 8 color selection was kinda boring when these cars were new.
as of now I am going to paint the car black because I am confident in my body work. I might change my mind 50 times. Problem with a wagon is you want a color that "pops" yet doesn't look over done.....that is a harder challenge than most people would think it is.
