Where is the best place to buy Quarter panel skins? Opgi has the best price I can find on them but they really stick it to you on shipping.

 

The best place is used OEM from the desert southwest. The Chinesium partial quarters that are sold by all the repro houses are crap and require a lot of hand massaging to fit anywhere near correctly. But at least they are a lot thinner than OEM, so they are easier to force into shape.
