looks like one of them OD transmissions - does anybody know if this is the same length as a standard 3 speed ( ie drive shaft length changes?)

That's a good deal for that transmission! I would buy that in a heart beat if it was close by

Yes, the 4 bolt side cover overdrive transmissions are the same length as the long tail shaft 3 speeds. I have two of the overdrive transmissions. The one currently in my truck came out of a 65 C10. I forget the count, but it has finer splines on the output shaft than the standard 3 speed I pulled out of my truck. The other overdrive that I have has the same spline count as the old 3 speed I pulled out.
I believe the output shaft spline count ran from 55-64 and then changed in 65. Another difference I noticed is that the input shaft necked down on my 55-64 overdrive trans but did not neck down on the 65 I put in the truck.
