'68-'72 3/4 ton automatic trucks generally have 4.10 gears and the center section will swap into your housing. Some spend a few years looking for the 4.10 gears. Depends on where you look and how lucky you are. I have had a few...last one I got I traded a rock crawler guy straight up for my 5.14 gear set. I also found one in a '70 dually truck with a V8 and 4 speed.
Nice score on the 261...
