3 speed tranny identification question

I got a 3 speed manuel from the wrecking yard out of a 61-66 F100. I need to replace the rear output shaft seal but there are three types of 3 speeds Borg warner t 57, t 59 and one other. the seals are different for all three. Can anyone tell me how to identify which 3spd tranny I have? are ther casting numbers I can cross? or maybee some identifying features to look for? any info would be helpfull.
Thanks all

Can find nothing on those models. Does it say BW on it? Or Ford?

Just post whatever is cast into it.

Also, is it a top-loaded trans with a tin cover and shifter arms on the driver side? Was it a 3 on tree job? Any OD attached?

thanks, I took the number off of the seal P/N 15005, I'll check around the tranny for a casing stamp. Also it is a top-loaded trans with a tin cover and shifter arms on the driver side. Floor shift when I bought it but I suspect an original column shift

There is a Ford 3 speed from that era, known as the "303" as it is 3.03 inches from one shaft to the other... All synchro, and has the tin top, top loaded, side shifters. Any 3 gear from that era would be column shift.

This looks to be a partial id chart, as only Bronco's are listed in the truck dept.

There are several versions of this trans, depending on application, and along with that, several ratio sets.
