Are you going to work it? and haul a load or just drive it around MT? I have a '46 GMC w/ a 302 and I have installed an NP-541 5 speed trans which bolts up to any GM bolt pattern(they also come w/ Ford, Dodge, Stude, etc.). However, you will need the trans w/ the short input shaft(std GM car length) and the bellhousing w/ the 5.125" std. retainer hole. The nice thing about this trans is it is a close ratio 4-speed w/ a granny low gear.
They are reasonably plentiful and cheap. The main identifying feature is they have 4 shift rails and an AL top cover. Make sure the pins that the shift lever rides on in the top of the cover are in good shape. They are exactly the same as an NP-435 but w/ 5 speeds. The shift ball shows the pattern but are frequently missing.
When you go to a wrecking yard to search for one, don't ask for one, they won't know what you are talking about and if they do know, they will ask an arm and a leg for it. Just poke around until you find one, and take it out yopurself if possible. Need a .875 box wrench for the bottom 2 bolts.
You can also hook them up to a transfer case if you are so inclined. I hooked one up to a Dana 20 case(early Bronco) and an NP-241.
