not sure about a '75, but i know that a 70 weighs in at something like 650 pounds give or take a bit, so with the doors off not a whole lot less, but we picked it up with a heavy duty motor hoist, with some heavy (i think 1.5in width) ratchet straps. it's really at least a two man job, 4 would be alot better though. check everything twice to make sure it's a taken loose. good luck with the project, take pictures, lotsa pictures.
