Think I'm screwed

And by the time you get a powertrain in there, suspension, steering, brakes, and exhaust; they're still not gonna let you license it, if you show up sitting on a milk-crate, lol.
In other words, you're looking at a big chunk of money in the overall.

I would suggest to remove the front wheels and check the frame integrity where the caster/ camber adjusters are. That is a common area where our As fail.... long before the T-bar crossmember goes. And also the rear shackle mounts.
