transmission swap

[o-dogg24]

I'm new to this site.i have a 71 gmc 3/4 ton 4x4 with a automatic transmission in it. I'd like to change it to a 4 speed.i have 2wd 3/4 ton 4 speeds but I don't think they are the same. can anyone tell me what I all need and have to do to get this done. I'm guessing I'll have to change gears ,and a lot of other things. thanks

To convert the 465 from 2 to 4wd you need to replace the main shaft, nut & lockwasher. The t-case adapter replaces the rear bearing retainer

x2, not hard to do if you have access to a press, better off finding a married unit ready to drop in though....

do you mean just find a 4x4 manual transmission and drive shaft. I'm little slow on the lingo your using.
