Trying to reduce body lift but cant?

[CNEPACE]

I recently acquired a 1969 K2500 fleetside 4 x 4. It has a 454 big block with a NP 208 transfer case and turbo 400 in it. The truck currently has a 4 inch body lift on it and a 4 inch suspension lift. My plan was to increase the suspension lift, and decrease the body lift. While I was under the truck today checking clearances I noticed the transfer case was only 1 inch below the cab. The engine and transfer case are all mounted properly but I am confused as to why there is only 1 inch of clearance over the transfer case with a 4 inch body lift. Has anybody on this combination (454/NP208)? Is it normal to have to lift the body to clear the transfer case?
