Gimbal ring, old style..

[pismo10]

I have a 1979 Mercruiser 260 that has the original gimbal ring with no tightening bolts. Mercruiser made a kit to replace this original model with a newer version that had two bolts at the top which could be tightened. I don't know what else was included in the kit other than a newer style gimbal ring.

Does anyone know the part number of this kit and where I could find one? Looking for a NOS one someplace.

Thanks.
