I was able to make some progress on my fastback recently. I'm still doing some exploratory surgery, but so far so good. So far, the only major rust is under what used to be the battery tray. Most of the problem spots for mustangs are in great shape:
The cowl side panels look great, I'm still gonna cut the top panel off just to check down inside:
I still have to disassemble the doors, remove the wiring harness, fuel/brake lines, and a few misc. parts then she'll be ready for media blasting.
