  shogun, Yes, they are both '39 transmissions. Be aware, though, that the serial numbers on the case say nothing about the internals. If I'm not mistaken, all gear sets will fit the '78 gearbox from '32 to '48 and up through '50 in the pickup trucks. The gerarsets will work, but only as sets, as the individual parts do not interchange. '32 - '35 sets had straight cut gears, '36 & up had helical cut, and the '39 introduced the superior synchromesh. 3 speed Pickups had open driveshafts from '49 up, and these gearsets also fit the 78 case.
