If the first transmission you referred to is a 3 speed top loader it is a model 303 fully synchronized 3 speed.  They came in very late Y powered trucks, Mustangs and other vehicles.  It is a good transmission which can have Mustang gears installed for better ratios.  Good to approx. 250 HP.  Floor shift linkage can be done away with if a shifting tower from a Jeep T-150 transmission is used, mounting the shifter and forks into the tranny top.

Mike, located in the Siskiyou mountains, Southern, OR 292 powered 1946 Ford 1/2 ton, '62 Mercury Meteor, '55 Country Squire (parting out), '64 Falcon, '54 Ford 600 tractor.

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,
