The 60-66 4x4's do seem to get lost in the shuffle. The toughest thing for me to find was info on the transfer case. I found a few pages of the repair manual at www.zianet.com/desertskies/truck.htm The pages are .pdf files so you'll need Acrobat Reader to view them. Acrobat is a free download. It's three pages; an exploded view of the transfer case, a disassembly page and, adjustment procedures. The only place I've found parts for the 221 are at www.drivetrain.com. they even have rebuild kits for the 221. Their shop is in Las Vegas, NV.
