So, I went & wire brushed the rear end & found this stamped on it. N K1224 Not sure if the "N" is part of it since its spaced kind like the way I typed it on here.So what I'm trying to find out is what the gear ratio of this rear is.I got it off of a
54 GMC Hydra-matic open drive.
Any info appreciated
Thanks
