Default Half Ton Transfer Case Info Needed

A friend of mine has a '64 C-10 4X4 with the rare Factory Original 3-Speed Trans. I've never seen one, but I'm going to guess that GMC had some as well.

His Transfer Case is making noise and is popping out of gear. Need to find out some info on it. Does a C-10 with a 3-Speed have the same Transfer Case as a 4-Speed Truck? Also wondering how available are parts for the Transfer Case he has and is there such a thing as a Rebuild Kit available? And what does it sound like is wrong with it? I'm asking on another board, but also hoping some of the experts on here could help as well.

Any helpful info would be appreciated.

Thanks

3 speed manual transmissions were standard even in Chevy and GMC 4X4's through out the 1960's. Many if not most 4X4's had the optional 4 speed as a 'creeper' first gear is a big advantage off-roading. Most Chevy and GMC 4X4's from 1960 to 1970 used the Rockwell T221. T221's make some noise particularly at highway speeds, but popping out of gear is never normal! Parts and kits are available for the T221, but not cheap. Not sure if these guys are any good (never used them myself) but looks like they have a lot of parts:

Thanks Bob.

In my research in the last few days, Torque King does seem to be the best place out there.

I ordered the axle flange gaskets from them for my Dana 60 full floater rear axle. They were the only one that had it.
