I did not buy one yet. I am still in the planning/budgeting stage.
In the meantime there is plenty of reading and measuring and thinking to do.
If you have a SBC engine with decent HP, then a T5 with a 0.72 OD gear will work well with a 3.73 rear axle (or numerically higher axle gear).
The inline 6 engines like the 0.86 OD gear.
The 1983-93 S10 T5s have a Muncie bolt pattern where it bolts to the bell.
The 1983-88 S10 T5s should have a cable style speedo connection. The 1989-93 S10 T5s have a Muncie bolt pattern with a VSS speedometer connection.
The 1994 and newer T5s have a FORD bolt pattern with a VSS style speedo connection. An adapter plate will be needed to bolt it to a Muncie pattern bell.
Don't forget that the GMC Sonoma trucks are likely to have the same combinations.
The T5 was not mated to the 4.3L engines.
Watch
