    Ok, so I recently serviced the rear end in the 5th (7 1/4 w/ 2.26 gear) and while I'm unimpressed with the gear ratio, I noticed 2 tags on the rear end. I expected one of them there for the gear ratio, but I wasn't expecting 2. I'll post the pics below. Looks like one of them says 2.2 (probably for the gear ratio) and the other looks to say 0274. Not sure what that's for.

    I should also mention that the gears looks factory fresh in this thing which I'm happy about

    Yes, the 2.2 is for 2.26 gears. The other tag,,,,,,,,,,,,,,,,possibly a date code? They're usually 4 digits anyways.

    That makes sense. The DOM for the car is February of 1984, so that fits perfectly.
