Dave-
I have a '66 'Cuda donor that I bought for the 273 / 4-speed combo. Largely a rust bucket, but the inner fender panels may be serviceable, especially the passenger side. The rear on the driver side, probably. Driver side front would need some patching.
You can have them for shipping cost.
I'm going out of town for a 2 weeks, but I can pull the parts, and send you pics when I get back.
