Yup. Totally different animal. At that point it's probably easier to just use a Ford RUG Toploader or a T5. Not sure if it's still available but Lakewood used to offer a Toploader pattern GM scattershield which would make it a bolt-in. I also recall Jeep using a bellhousing for a 231 with a T19(?) Behind it, making a BOP to Ford transmission possible.
