Morale Problem
I wouldn't spend a TON of money on it, but take your time and find the parts you need at the right price and you'll have a cool car. You don't have to make it a sleeper either, you could use some stripes or whatever you want to put some flash on it. If your whining about people dissing YOUR A-body, your whining to the wrong people. Everyone here with an A-body has probably heard it before, whether they have a 69 440 'Cuda or a /6 63 Dart, "what a grandma car, P.O.S. waste of money" ... Yeah, OK, go spend 100k on your e-body. The fact is, most any A-body can whip the other body styles with similiar mods. In high school I drove a '70 Swinger, pale yellow 318 auto car with a T5 bronze interior. Yeah, my grandmother bought it new so it really was a grandma car. Guess what, it got more looks than the Camaros and mustangs and outran most of them too. It was unique and you'll likely have the only Valiant Broughm anywhere you go.
I have a 73 Dart sedan parts car with lots of trim left on it. Let me know if you need anything.
