David - You may want to consider changing the color of some of those panels via paint if the price to replace is excessive, particularly the low wear ones? I just did an interior of a 914 and used vinyl paint along with paint prep and adhesion promoter and went from black to tan and it came out great. At this point time will tell how well it holds up, but things like the door panels cam out really good. If I could go from black to tan you should have no problem going from tan to black? Good luck ...
These were all black at one time!
