Cab 12 Alteration???

[Bob Carriere]

The whole issue is to be able to fit the tranny WITHOUT relocating the transfer case. On a 2 wheel drive C15 it is not an issue.

In the early 60s GM had the 261 engine in GM van bodies and they used a particular 3 speed tranny that had a very short tail shaft..... that's the beast that must be located. Also believe that the tail shaft on most GM 3 speed could be changed form short, med. or long dependent on the vehicle it was installed in. It apparently fits in the CMP space using a very short drive shaft to the t case. I have not seen one and am not sure what model to ask for. Need to befriend a auto tranny rebuild guy that is old enough to have worked on them. Early 261 van engines ALSO had a hydraulic operated clutch that was on the right hand side of the bell housing identical to the CMP.

1960 GM vehicles are already considered antiques.
