Avette,
The Chevy and dodge pickups run a New Venture NV4500 5 speed. This is a transmission that came about by the merging of the New Process plant, and the Muncie plant... it was a "joint venture" between gm and dodge.
There are subtle differences in the transmissions from year to year, and some versions swap eazier into certain applications. You will almost certainly need a new bellhousing, or adapter plate unless you could find the 93 chevy version. Only the Dodge 2wd version from 94-97 can be ran with a mechanical speedo. The Dodge version has an input shaft that is 1 inch longer than the chevy version. Adapter plates are available to mate them to the chevy bellhousing so you won't have to mess with your clutch linkage.
There is also the possibility of finding a used 1 with the gear venders overdrive. That setup would give you a 10 speed.
