[Oletrucks] 3 speed overdrive conversion

[Kinderlehrer]

Thanks Mark. I have the 4 speed installed now - anyone know if that is that
the same length as the 3 speed? Bob

I happen to have the 3-speed out of my 58 Suburban stored next to the 
3-speed OD I plan to put back into it. As far as I can tell, they are 
identical in length, 22 inches from trans-to-bellhousing mount to end of 
tail piece plus 1/2 inch out the back for the splines on the shaft.
