I can pick up a wrecked 89/90 2wd reg cab cummins with a 5spd for cheap, only problem its a 2wd. I know the trans are different and I wouldn't mind a 6spd anyway. This will be for my next conversion projetc when I'm done with this one. So how can I make this getrag accept a transfer case? I have a spare 92 auto transfer case. Would the 6spd NV5400 bolt on? They require a special T case I believe too.
