A later 5 spd is a direct replacement for the 4spd,
GM went cheap on the carb 4cyl S10 it was a fleet rig in their plan.

It would be interesting to do a actual axle gear swap if you could find one of the 4x4 5 spds and put it in the truck, the 4x4 had a lower 1st gear in most of them... SO you can get it moving with a higher axle gear.

Oh and here is a tidbit after some googling...
Axle Gearing codes from the S10 forum!

2.73 = GU2
3.08 = GU4
3.42 = GU6
3.73 = GT4, GQ1
4.10 = GT5

If it has a motor its worth playing with.......
