1994 f150, ISB 3.9 to be swapped in

Is there any difference between the ISB 3.9 to the 4BT in how the transmission is spaced? Im trying to adapt a early Gm NV4500 to a ISB 3.9 Talked to the guys at quick draw they say you cant use the early NV4500 with there kit.
They do have a kit that works with the early Nv4500 for the B series. But says the 4BT wont work with the ISB 3.9 Im so confused.
