A 1971 R/T I am offering before I strip it. Look on fbbo for post
$7k parts car? Yeah no, you won't get that unless you sell every single nut and bolt and it'll take years. For the time and effort involved you'd be on the losing end. Not to mention if you had $7k to buy the car you should have just bought the parts you needed and left the car for someone else.
That's a very desirable car, even if the market is a little smaller for the 71+ B's. If it's mostly solid you can get more than $7k for it as it sits. Just list it on eBay and turn a profit without lifting a finger.
Regardless, it should be a crime to part that car.
