Frame differences?

[BADAZ chevy guy]

First off, I want to thank everyone for your replies. A lot of good information here. However, curiosity got the best of me and I drove to Salt Lake to actually look at what I was dealing with. Although it could be done, the main reason I wanted another frame was to make things easier during my build. Starting with a 4x4 frame isn't going to do this for me. There's just to many modifications I'd have to make.
