Suburban frame question

[72 5500]

I am thinking about using a 80's suburban frame to convert my two wheel 64 panel to four wheel drive. I am not sure if the suburban frame has the hump in the back of the frame like the pickup frames do. The hump is the main clearance problem between the body and the frame. I do not want to have a body lift to make it fit. Can anyone tell how long the wheelbase is on a suburban and does anyone have any pics of there frame???

I know, I know everyone is telling me to bolt everything to the original frame and be done with it. I'm thinking it will be just as easy to shorten the frame and drive shaft a few inches along with making a few new body mounts.
