Did the pics show up now? My media page was set to private for some reason.

Nice, I can see the pics. Looks like you got a standard 10 bolt 3/4 ton front axle. I can't tell what transfer from the pics. If you can get a shot of the trans/transfer I could tell what model. Also should be able to tell from a closeup of the transfer case shifter knob. It looks similar to my NP205 shifter but could be a 203 depending on what shift positions you have. If you have hi-lock and lo-lock it is a 203. If you only have 2Hi, 4Hi, and 4Lo its probably a 205

Here is some pics of the transfer case and shifter inside. It has the code C-99404 with AA under the code. I take possession of the truck in about a week. I can't wait to start tearing into it. There are so many fluid leaks !!

That's a 70-77 GM NP205 with a slip yoke eliminator... it's about the most bulletproof and desirable off-road setup you could have.
