This is out of an '82 s10 - dimensionally same as a T5 but no 5th gear - lighter weight and a bit more compact - mount is a little further forward with no bulge on either side of the tail where 5th normally is- it has a mechanical speedometer hook up - 4.03 first gear with 1:1 4th - same input shaft and bolt pattern as an '82-'93 s10 T5 so can use all available T5 adapters or bolt direct to chevy bell. Works great with a 3.08 or higher (lower numerically) gear or tall tires - depending on rear gear ratio, a car set up with an s10 T5 often has either a too low overall takeoff ratio and 1st gear is way too short, or it cant pull OD at less than 80MPH.....Its the trans on the right in the pic and it includes the shifter - turns over freely and shifts through the gears - for comparison the trans in the middle is an '87 Camaro v8 T5 with a '93 s10 tail and the one to the left is a saginaw 4 speed
