On eBay now is an open differential that might be a 3.90:

 

1968 - 1976 BMW 2002 E10 Open Differential

WWW.EBAY.COM

---

Good condition 1968 - 1976 BMW 2002 E10 open differential. Cleaned, degreased and painted. From a 1976. Mounting bolts not shown, but included.

 

Since they only appeared on 49-state versions of U.S. 1976 model 2002’s, they are not common.

 

This poor thing looks like it was dipped in a bucket of black paint, so the stampings and casting date are a bit hazy.

 

But, looking at the first photo below, I believe we’re looking at “10    39” for the pinion and ring gear teeth, yielding the magic 3.90. Below that is a “3” for March and, possibly, a “6” for 1976. If so, the unit was manufactured March 1976. Looking at the second photo, the housing’s casting date is pretty hard to read: I see anything from May 24, 1975 (if “24575”) to March 24, 1976 (if “24376”).

 

In addition, the seller says it came out of a 1976, but lots of ‘02 differentials have been swapped by now. So I wouldn’t rely solely on that historical tidbit! 

 

Caveats: most ‘02 differentials still retain their original, factory ratios — OK, they’re mostly 3.64, except for 1600-2’s that had 4.10’s or 4.11’s — but occasionally the ring and pinion gears have been swapped to a different ratio. Open it to verify the gearing. And, who knows the mileage, history, or condition of a 46-year-old differential without having a professional inspect the innards? 😯🙄

 

Regards,

 

Steve

Great read on this diff - I will contact the seller to see if he can send better pics of the stamping on the case - thanks!

I have black rear window hinges and have a very nice 3.91 E21 open differential that is in much better cosmetic and mechanical shape than any original 3.90 from 76.  The adaptation of the E21 differential is not difficult and has been documented by several if you do a search.
