I bought a real nice set of NOS ones, with NOS woodgrain inserts off ebay a few months ago. Mine were the '73-76 style, which is a little harder to come across...if you have 6 or 9 months of patiance, I'm sure a pair would eventually show up there...Do you need the whole panel with trim and all replaced...or just the door panel? The OEM trim/inserts are much harder to come by (and repair for that matter), than the panel itself..Panels themselves can often simply be painted with a good quality paint (made for plastic)...
