4spd /6 Question

he should check to see if the bellhousing would mate with his tranny,
The only "Cave-eat" would be the bearing retainer on the front of the tranny. Theres 2 (I tihnk) sizes. The bellhousing would have to have the hole enlarged if it is the small one to mate with a big bearing retainer. A Lakewood scatter sheild has a ring to reduce the size of the hole should you need a scattersheild.

A dead give away that it is an overdrive is the fliped upside down lever.
