...a 3/4 ton is to a 1/2 ton as a Nova is to a Corvette. Sounds like a question on the GRE...
Gary,
Yes you can still do all kinds of good things with a 3/4 ton even though most of the aftermarket stuff is for the 1/2 ton. Yes, the body parts are the same. You can paint it, restore it, put a bunch of new parts on it. You can get wheels for it. You can put a hydrovac on it and have yourself power brakes. You can put a power steering kit on it. You can do things to the suspension. Change the trans, put an entirely different rear end in it. You can put any number of power plants and transmissions in it. You can install airconditioning, an air horn and colored neon lights. And, you will be able to carry more weight in it. Yay! Great day in the UK!
