Another power window car! Cool I'm jealous! What color combo? 66-67's parts are hard to find and expensive when you do. Also the two cars look similar but many parts are unique to each year and not interchangeable.
You WILL spend more than the car is worth if you do a ground-up and pay someone. If your hands on you'll save some cash and maybe make a little. The fan base for these two years is small in my opinion so If your looking to flip it you won't have a high demand car.
When I see the prices for some cars today it seems like a steal. I know after doing ours just how much you can spend doing a car nowadays. If you have a rare, one off piece maybe. I always tell people find a nice car that's done and putz with it!
