Bah, who needs AC/heat. Save your money. Jerk everything out and have yourself a decent weekend driver/track car.:biggrin:
I'd seriously consider this at least. No one is going to pay premium for a car that had an electrical fire-even one fully restored with $xx,xxx put back in to it. I can only imagine the issues you will have with wiring behind the dash, A/C, radio wiring, etc.
I would have ripped that dash, the ac compressor, heater core, all that junk out the first weekend. It's going to be a very long and expensive process piecing that all back together, if you go for it best of luck! Getting odors out without a complete strip down to the aluminum is going to be tricky as well
