You DON'T want the repro panels. A friend bought some for his car and I had to make them work as best I could. I did take pics if anyone ever wants to see how bad they really are.
I didn't think to take pics at the time I was working on the car (and I no longer own it) but I redid the panels on my '68 B'cuda 'vert when I changed the interior from black to white. I kept the top part black but painted the textured part white. Since my new seat covers and door panels were pearl white I wanted to try to match them as close as I could.
All of the originals I have seen were a shade of white that didn't really match the rest of the interior, maybe when new, but I doubt it.
Anyway I first painted them solid bright white for coverage. I then went over that with a couple of light coats of a white pearl midcoat I had on the shelf. I had some old fashioned white pearl in a little jar like they used years ago on custom jobs so I added some of that to the midcoat pearl also and some to the clear coat.
I used light coats so the thickness wasn't as great as it sounds. I thought they turned out really good, and they matched the upholstery.
Below is the only pic I have of the interior and you can just see the bit that wraps around the pinchweld.
