Just ran into another parts source today. He has at least 5 FC's with a lot of the hard to find parts still in them. His prices are fair too. He has a ton of old cars and pickups there. Most have mid-west rust, but some still look restorable.

As a reminder, Ira's in Madras, Oregon also had 4-5 FC's two years ago.
