My thoughts, if you have a good frame and a clear title, everything else can be purchased. Salvage everything you can from both and plan to buy the rest. You could rebuild one. But as everyone said, it takes TIME and MONEY. Lots of time. Those build shows are like "So, Tom and Jerry are going to replace the cowl". Go to commercial and when you come back the cowl is in place. What they don't tell you is they filmed that sequence for three weeks and Jerry beat the hell out of Tom because he got so fed up with alignment problems and snapped.
Seriously though, I would tackle something like that again, even after going through it all once before. You bring something like that back to life and doctors won't be able to get the smile off your face.
