I know you guys answer these questions all the time so hopefully you won't mind yet another. I'm trying to help a guy ID his axle, got the following; 2GM14012196 13 42 12 80 so if I'm correct you divide 42 by 12? That would mean a 3:50 ratio. Does that even exist, or did he give me the wrong numbers? Along the same lines, I'm pretty sure it is a 14 sf as it has 8 bolt wheels, 14 bolts on the pumpkin but what throws me off is that the pumpkin is definitely smaller than my 14bff, most notably the bottom edge appears to have less of a 'point'. Does the semi float have a different pumpkin, or is this another axle? Thanks guys. Jason.
