Hello, I recntly purchased a 1973 Mach 1 off eBay when I was in Iraq. I got home and wanted to start a restoration on the vehicle. This is the first vehicle I've ever tried to do this with. Mechanically, she's sound. However it seems to have some rust on the frame. I want to know how bad the rust is, if it's repairable and how I can go about it. I feel confident working on engines and doing some interior work but I think I should leave the frame work to professionals(Spelt wrong). I see various rust bubbles on the outside, the paint job is decent and the engine compartment is clean for the most part.
