What part of Dallas? I don't know if they still do, but once upon a time Merriman Park Automotive did good body work & paint on some classic cars/trucks. They're not on the beaten path...sort of hidden behind Jake's on Skillman (north of where it intersects Abrams). Nice people who run it and honest. Truthfully, you're going to need to find a shop similar to that. I could tell you some places to avoid, but it isn't my style. Another possibility (although I don't know if they paint whole cars any more) is Orbit Automotive (on Forest Lane). Very honest people and good friends of mine for a long time. The owner has a terrific knowledge of old cars.
