1967 barracuda fastback resto or mod?

Although rare, '67 fastbacks are certainly not exceptionly valueable. If you want to restore it 100%, go ahead. If you want to modernize it, go ahead. If you want to leave it alone and repair/replace, go ahead. I have been in the Mopar hobby/parts business since 1984 and in my experience you will NOT lose value if you restify your car. If it was a matching numbers B/B or a Super Stock or some other historically significant piece, then, that's a different story. DO YOUR THING to the best of your ability. Take PRIDE in yourself, your car and Mopars. GO FOR IT
