They did use the T5 behind the 4 bangers that late.
Yes, they are world class,
They have 26 input splines,
has the longer S10 input shaft length,
They are electric speedo only,
Might have a 4.03 first gear,
They most likely have the Ford bolt pattern.
Assuming the Ford pattern, then No, It won't work with a typical Chevy bellhousing unless you modify it by re-tapping the top holes and welding on a tab accross the bottom of the bellhousing to pick up the bottom two bolts.
Other option is to find an early 1980's Jeep 2.5L bellhousing which is a Chevy bell with the Ford pattern. You will need to use the smaller 153 tooth flywheel, not the 168. The center hole is larger than 4 11/16", so either an adapter ring needs to be made, or you will need to swap out the input collar. The Ford T5 collar I have will fit the Chevy T5, but it is a little larger than the hole in this bellhousing, so getting it turned down would be an option. Not sure what the collars on the Jeep T5's are for diameter.
