The way I pulled my '50 3spd(more than once) was to get the truck high as I could on jack stands, disconnected all the shift lingage(column), disconnect the bell torque tube coupling, than wrapped a sling around the trans supported by a short length 2x4 spanning the transmision opening. Unbolted the trans, wiggled it out,(you may have to shift the torque tube a little, but it'll take it without damage). Once free and supported by the sling, slide a jack under it and take the weight off the sling and 2x4.Slide out the 2x4 and lower the trans. Sounds long winded, but it worked for me.
