Thanks tim is there any markings on it like x 12, z or a12?

Should be A12,narrow silver band. The X12 and Z12 are the dual point type with wider,gold band.

The distributor is marked C8ZF-12127-A. It will have a dual style vacuum advance

Is that a service part?

I thought the front vacuum nipple threaded into the housing?

Per MPC, the C8ZF-A should use a DD#307 diaphragm unit. CORRECTED POST
