Yes, but not very easily. It would be eazier to use the 5 speed out of a 94-97 dodge 3/4 ton or 1 ton. Both the gm and dodge used a transmission called the New Venture 4500 or NV4500. The New Venture plant was formed with the merging of the Muncie transmission plant and the New Process transmission plant. It was formed as a "joint venture" between GM and Dodge.

Why the dodge version?
The dodge NV4500 is easier to swap into older gm vehicles because it can more easily be adapted to run a mechanical speedometer. The input shaft of the dodge version is 1 inch longer than the input shaft of the gm version. The extra length allows you to use an adapter plate that is 1 inch thick to go from the NV4500 to the gm bellhousing. The NV4500 that was used in the gm trucks does not have the typical gm bellhousing patern, so it will not bolt up to the older gm bellhousings.

The 94-97 dodge 2wd nv4500 transmission is the one needed to run the mechanical speedo... oops, you mentioned a 2 speed rearend... I am not sure where the speedo gear lives on that setup.

There is plenty of info about this transmission on the internet. Do a search. I have swapped this transmission into a 59 gmc 1/2 ton. They are rated for moving about 16,000 lbs
