My uncle went to sell parts. He sold the drivetrain related parts he took, but no sheet metal. He had some nice fenders and doors for 68-70 B bodies and didn't even have anyone look at them surprisingly. From what he could tell, he said it didn't seem like body parts were selling very well?
He sold a B body Dana 60 and a '70 E body pistol grip for me...sold them pretty quick.
I didn't sell any sheet metal either, and a pair of AMD quarters for a 67 Dart are still in the package. I was $100 cheaper than anyone else there on them too...
