Rear Axle codes?
I did a few google searches and nothing came up.
Is there any where I could go to identified the gears in the rear end? The axle code starts with KAD and is out of a 74 2wd C10. Did the 73-74 12 bolts come with the posi option? |

1974 KAD was a C10 axle equipped with a locking diff and 3.07 gears. You can see that some of the 73 P & G series Vans had positraction. so... GM differentiated between the locker and posi. I don't believe the 73-91 CK trucks got Positrac. Don't use limited slip additive in this axle if it has the original Eaton Locker. http://gmpartswiki.com/getpage?pageid=60427

Re: Rear Axle codes?
After 44 - ish years there's really no telling what's in there.
Best bet is to pull the cover and count teeth and replace the gear lube while you are at it. K
