Will 2wd upper and lower control arms fit a 4wd Frame? What if I cut all tabs off and re-fab new tabs? Are the frame rails the same height?

What are some of the lowest numbers people have gotten out of the 4wd setup with the shafts removed, without using bags?

I have done quite a bit of searching, and really have alot of questions. All i can find is people asking the same questions, not actually getting things done.

I am a fabricator, and have tons of ambition for this project. If i had money, id just buy a 2wd, but that money is not in the budget, and my truck is too mint to get rid of.
