I gotta ask, On something like that limo, why not get a divorced case, and put it behind a two wheel drive tranny and use the divorced case as a carrier bearing for the rear shaft? I mean, you would have a shorter driveshaft for the rear, and have functional 4wd, especially if you had an electric shift divorced case? shoot, better yet, If you ARENT wanting 4wd, fab up a just the front stuff with two stock length driveshafts.... one to the lowered tcase and one to the front axle...
great Ive contributed to thhe disgrace, HEY if you did it right, you could hook a giant jacuzzi pump to the rear output, when your parked you would just put it in 2wd with the ebrake on and still have your PTO jacuzzi pump
