I recently acquired a 3 speed manual transmission.  I has 17-AF-7006A cast into it.  It has a floor shift kit on it.  I also acquired a T-10B-1 that has T10B-7 on the tail shaft.  It may be a Mustang application ? ...also acquired a T-86 OD that us a top loader, not sure what year that might be.   Whay I want is a T-85 OD for my 57.  I have two T-85's, but they have a U joint output, probably a truck or Studebaker application. 

Any help appreciated,
