Differential Decode
Can anyone help me decode the numbers on my differential. It is on a 63 however this is not the first non original part that I have found.
3830303
3818753-N
now the tricky part....
AM 8 21 64 stamped on the bottom. I think the first two letters are the gear ratio. The 8 is barely legible and the 6 is also barely legible.
Their is also another casting date either B 8 4 or 8 8 4. I would think it would be the later if the stamp is 8/21/64.
Any help would be appreciated.
Thanks

Then I guess the casting code is B 4 4 and the stamp is a 3 21 64 and not an 8. Seems like a long time (over a month) from the time it was cast to the time it was stamped/built?
