Got under it last night at midnight after work. Had so little time lately but itching to work on it. I see a tag on the rear but tough to read. Need to clean it up. That pumpkin is seeping a bit so I've been planning on popping the cap and cleaning it out and filling it with clean gear oil anyhow, along with front, and hopefully can read tag.

Also, it looks like I have 8.25's. Does that sound right? It's a 150 but 1/2 ton 1979. Also, I did check speedo adapter and it's dry. It connects into a block, that connects into the transfer case. The black had a small crack, but it's dry.
