I own a 02' Denali quadrasteer, I bought it new and it is my baby. I have supercharged it and done many interior mods. Unfortunately the 02' Denali's only came in an extended cab version and I really want to swap it for a crew cab. I know there might be modifications that need to be done to the bed but I figured this would be easier than swapping the engine/tranny/rear axle on a later model crew cab Denali. If the body mounts line up I think the swap would be fairly easy. Anyone with expertise on this subject would be much appreciated. I have found a couple other threads with similar desires but none of them are contending with the quadrasteer option. Thanks in advance.
