Suburban vs C10

[bruin_d]

I currently have a C10 that has a cab that is completely shot. I have been looking for a cab and eventually just decided to look for a whole truck. I found a suburban for sale that I want to buy. I have the porterbuilt front cross member, rack and pinion, baer discs all the way around, and the rear drop member trailing arm setup on the way. My question is, how interchangeable are all of the parts? Will all of my suspension parts change over? Thanks in advance.
