So I have a 1991 Fox Mustang GT Convertible it came factory with the aod I am in the process of swapping in a T5 and hydraulic clutch I took out the VSS and it has the pictured gear on it I can not find any info on it from a count it has 16 teeth and is unlike most driven gears I can find online it is dark green in color my rear end has no tag on it so I do not know if it has factory gears my door tag indicates 3.27 Gears from the factory but a bunch of other stuff on the tag in inaccurate to the car like the tag saying it came with a white top where as my car has a black top (needs a new top and frame the frame is broken)
