Duster dash pad

The hard shell covers look fine. I put one in our 1st 67 many years ago. It seemed to be a nearly unbreakable plastic. Dying wasn't cheap since black wont dye red without going through a neutral (beige) coat first.
Personally, I expect to spend a few hundred having the cap restored for my ragtop project car. I will most lilely throw a cap over it too, just to protect my investment.
