If you do fix it, remember it's so far gone you can do whatever you want to it. You're not ruining anything if you make it into a race car, or a modern street driver with a tube K frame, efi, 4 wheel discs, etc. Do whatever you want to it. But if you don't want to fix it up, sell it to someone else who will. I bet you'd be able to sell the thing whole for the same amount of money you'd get from parting it, especially if stuff is missing from it already.
