I agree with all of your sentiment. I have been into classic Mustangs for the last 20 years, I am (IMHO) a near expert on values of them, and what is sacrilege to do to what cars. Bought the 70 Bronco a few years ago and have been watching them closely since. Still learning, but I figured as much as you said, so far as the mods I'm doing not being something to destroy the vehicle's value.
I have a nice poly barn and plenty of space to keep extra parts (still have boxes of parts to Mustangs I haven't owned in 12 years. ) so storage is no problem.
I'm going to start with the PDB on it, then when I rebuild the 302, drop it in with a C4 and the power steering. Should make it a nice little cruiser for the wife.
This is the car. It's being shipped in later this week or next.
