Woah! 65 Dart body over a BMW

Does he still have the floor pan? Seems to me some frame braces and a 340 would have been a lot easier. Hope he has better luck with his BMW parts than I did with my 2010 328i convertible. It was a very unreliable car. I sold it just before it went out of warranty. Loved to drive it. Didn’t want to have to pay for another $3000 headlight or $5000 back seat A/C evaporator out of my own pocket.
