Duster dash pad
If you chose to go the dash pad route, I know that you can get a new pad from Harden's Muscle Car World. I bought one from them a few years ago and put it on the wife's Swinger. If interested you can see what those look like by checking out pictures of her car in my photo gallery here at FABO. Decent, but not an exact replacement. Re-Pops of anything seldom are... Current cost is $289 each. Just FYI.
