Diablodoc, The gearbox has a rear transfer case integrated. The input rear driveshaft is inside the bellhousing (see attached pic). There`s a driveshaft that runs along side of the engine block, to a rear diff, that mounts to the engine block. All I need to do now... is have adapters made for OEM axles to C5 hubs. The output shaft in the front, is for FWD. Which I`m going to delete. Need to make a mounting bracket in place of the front driveshaft. Otherwise (without front driveshaft) the gearbox will bounce on the chassis. FWD delete drops 200lbs, less horsepower loss, and adds 30% more to clutch life.
