Thanks guys, I'm sure some help will be needed down the road. Yes dlezama white interiors look good, but mine have just about turned to dust, I recently picked up a set of good panels (thanks to this site and socalconcours77) for one car.
Yeah, for some reason black plastics are the strongest, and white and light blue just turn into dust. But careful dyeing, or painting with base lacquer and matte clear will allow you to recycle other colors. Use adhesion promoter before any dyeing or repaint. Does wonders. There is also a very strong white plastic primer in cans, you may want to try that, my interiors are red and black so I decided against, but it might work well for you. Also be prepared for extensive touchups after reassembly, and a relatively careful use of the interior.
Parts prone to heavy use (such as seatbelt clips or seatbelt pods), you might want to paint using the matching color.
Also remember to match the original white, its a slightly creamy, off-white. Sometimes its easy to assume they were originally pure white but no. Keep in mind to repaint the interior of the hatch same white, too, in a satin finish.
