Opinions on a restoration

I would go with car one for a restoration, simply because it has a title, and a V8 K with a straight frame, i have never worked on a frame, but im pretty sure it would be a massive pain, plus having a V8 k member is a huge plus.
I would probably see if i could buy the '72 for a parts car though. If it has good metal for replacements, thats a lot of money saved. Plus you could transplant the front clip, if you wanted to go that route.
