Cool, neat to see you're making your own!
I still have to ask about the 2x2x4... why the 4"? ...can you explain how you plan to orientate the tube? With bolts and all?
Are you planning on just using the tubing directly between the body and frame, with no spacer bushings? I guess this might work, because then the body bolt might be long enough to go all the way through.. (the 2" side anyway). But I don't think I would recommend it because there will be essentially NO give between your body and frame. Plus then you'd only be getting about a 1.5" body lift because there was already a stock .5" spacer bushing in there...
I would think the 4" would make it hard to get a wrench inside to tighten town the nuts?
I guess I am confused...
(I probably sound like it)
Someday when the opportunity presents itself I'll have to check out a 2 door's body mounts. I thought the mounts were pretty much the same, but there were only 6, not 8. So you could follow my article, and omit two mounts.
I've probably had a 4 door apart and together about 6 or 7 times while I've either put a body lift on one, or fixed a body lift on one.
Hmm...
