Hey Fellas, trying to sell this '39 Ford trans to a fellow Hot Rodder up in GA. Will this or can this be adapted to use with an open driveline configuration?? Will he have to get a different rear housing?? Thanks.
You will need the output shaft and the rear housing (the one with the chunk missing) and gasket. The U-joint, sliding forward/reverse gear and bearing can be re-used. Be aware that these open drives have a speedometer cable connection that points straight up toward the floor. Can be a clearance problem and your buyer might need a 90 degree speedo drive. That would be his problem, though.
As others have noted, Ford made the parts you need, since '42--'50 Ford pickups use an open drive version of the '39 toploader. Same trans case 78- prefix part number first used in '37. '42-'47 pickups use an open drive shaft version of the old Ford banjo rear.
