That's called "sending a boy to do a man's job". After seeing several M-2 suspension installations, I'm convinced that all they're good for is holding up the front end of a custom truck at a car show. If you're going to drive it regularly, you need to start with something designed to carry more weight, and pay very close attention to the geometry as it's installed. A narrowed 1/2 ton IFS or something from a Camaro or a Nova seems like a much better choice.
