I have been cleaning up my rear axle that came out of a 73 gran torino and I ran across this number, 18, stamped on both axle tubes. It's stamped right in front of the axle flange and it goes all the way around. Here is the a photo, please let me know if it won't allow you to view it:

Anybody know what it stands for as I've ask a few people around here and they have no clue what it stands for. Since it was F*rd guys I was asking that didn't know I'm assuming it's not very important but want to make sure before I disregard it. I also did some research on the net and nothing came up either.

Thanks,

Carson
