66 273 to a 65 A833 and all into 67 dart?

I think the best idea is to purchase a donor-car that already has everything you need;

By the time you collect all that you will need, I think you would be bucks ahead, and then you might still have stuff to sell when yur done.....

Whatever you do, make sure you get V-8 pedals, which are set up for a 10.5 clutch.
