Decoding rear end housing numbers
While I was under the car yesterday, I got the numbers off the rear end housing. Cast into the cover is: 3871375
Stamped into the bottom of the rear end is OC124W7E1. The "7" and the "E" were hard to make out, so they could be something else.
I think the OC code is for 3.70 Positraction.
W is for Warren plant?
124 is date of build?
I don't know what 7E1 means?

I can't help a fellow '77 owner :bb
I looked through everything I've got, but all I can do is confirm that OC is the 3.70 rear.
Oh well, I can get your post TTT.
