How far gone is too far gone?

I commented on the Farcebook post you put up. I parted out over 300 Darts in the last 42 years and have come to regret a lot of that over the last 10 years or so since you can buy most sheet metal parts to fix them nowadays. Numbers matching true musclecars such as this are getting harder to find, and there are people who will get you the drivetrain you need for your 74 for the price of the leaving the 70 together. I know I would do just that if I didn't already have 13 project Darts laying around! Before you start to part it out, offer it up on here and Farcebook and ad that you would be interested in finding a good drivetrain to trade...That's my two cents...
You have an awesome place that is so fun to look around and gawk !
