I could be mistaken, but I don't think there's a difference between the SM420 found in 2wd & 4wd GM trucks from the factory. The 4wd trucks all used divorced transfer cases, which used 2wd transmissions.
I believe there's 2 (or maybe 3) variants of spline count that were used, but from what I remember they all have a 2wd yoke.
There's a few places that make 4wd adapters to mount some of the popular transfer cases to the SM420 and essentially make it like a married transfer case, but that might be hard to find already done for your setup. You might check Jeep and Toyota forum's classifieds as well, the short wheelbase crowd tend to be the ones making that conversation.
The SM465 was offered in a 2wd and 4wd variant if that helps any.
