Hi Dan,

It was near the top right of the cover, found it when i was prepping to paint the cover. I don't know if this a normal stamp or not, maybe someone with more knowledge could shed some light on this.

I have 2 rear ends for a javelin. one is a 73 rear with an "A" on the flat case and the other is a 71 rear with a "O" on the flat of the case. what ratio are these? I plan to use a mopar rearend or a ford 9 inch as these amc rear ends are really weak looking. Small axle tubes weak 2 part hubs and 40+ years is too much for me. Steve in Ga.
amc is the torque master!
