No offense , but I'll bet thats still close to 1000 lbs

do what you want, I am just thinking safety first

brother to a buddy of mine died when his floor jack blew out,,,,, with him under the car.It didn't just go down slowly, it fell asap.

And it was just a 1969 Camaro shell. NO interior, engine, trans, no doors or decklid. Just a bare shell with ft and rear suspensions in it(about what you have in the car pictured)
