12 Bolt Axle Length question?

[max 02]

My sons buddy has a 67 C10 with a 6 lug 12 bolt rear end. He converted the front to 5 lug disk.
I told him that I have a set of 5 lug axles out of a 79 C10 12 bolt I would give him.
Any body know if they are the same length?

I've converted a few early trucks to 5 lug. from what I remember, all 12 bolt 2x truck axles are the same length.

Sweet! The young guy was thinking the axles from the 79 might be to long. I wasn`t sure. To bad I chucked out the drums that go with them.

Just found this on google.... Looks like they will be 1”1/2 to long per side.

I am fairly confident that what you found is correct. I tried it back in 1986 with my old '68 C10. I had axles out of a '72. No go.
I had to swap the while axle housing.
If you can't find the correct axle, I believe that it was Early Classic that had a bracket for the right side at the U bolt, and a longer panhard bar to get around not having the stud on the differential center section.

See if this works. It does state that it was designed for lowered trucks, however.

Ok! That link worked. His truck has air bags in the back. He needs to redo his exhaust to go lower though.
