The adapter plate is 1.625” in length and is manufactured from 356-T6 heat treated aluminum alloy. Included in the adapter plate kit you will receive an adapter plate, 4.686” bearing retainer, pilot bushing, fastening hardware, and adapter instructions.
- Chevy/GM Small Block V8
- Chevy/GM 4.3L V6
- Buick 225 & 231 V6
With our adapter plates, we utilize a new front bearing retainer to obtain proper bell housing alignment. Chevy adapter plates we use a small index of 4.686”, if your bell housing utilizes the larger 5.125 index diameter you will also require PN716078
The T-15 is a 3 speed manual transmission and can be identified by a case length of 10.00”. T15 or 1307 is normally cast on the side of the case. And 8 bolts hold the shift cover to the top of the case. This is probably one of the strongest of the 3 speeds transmission. The T-15 was only used behind V8 equipped CJ’s and Jeep trucks.
