Re: Help ID this rear end

Look it up in the parts books...

KAN axle code was used twice on the squarebody trucks between 1974 & 1991.
8.75" locking rear with 3.08 gears from a 1974 K10
8.75" open rear with 3.07 gears from a 1979 C or K10 with JB5 brakes

8.75" is a twelve bolt axle.

It originally came with 3.07 or 3.08 gears. It's also 40 years old or older and gears are easy to change.
