Found the 3.89 I was looking for, and it already has some type of limited slip unit in it. No mfg marks, other than a number. Does anyone recognize it - second photo? It was assembled by an outfit in Columbus Ohio that actually put their tag on the case - last photo.<div class=""><br class=""></div><div class="">Second, I have some spare differentials I’ll never use that are up for grabs - free if you pay for shipping. I think I’m going to keep the 3.64, but I have a 3.27 and two 4.11s. No rear case, no stub axles, just like the ones in the photo. Gears look good on all, can’t speak for anything else but they should be rebuildable.</div><div class=""><br class=""></div><div class="">let me know if you are interested. <br class=""><div><div class=""><div class=""><br class=""><br class=""><img class="" apple-inline="yes" id="A9541FCE-3129-412D-860B-FD4BE6139A94" src="cid:AB14B5EA-34AF-4027-ABBE-77F8EA5A77CC"><br class=""><br class=""><br class=""><img class="" apple-inline="yes" id="26987A37-B8F5-4D6A-AF20-745C34F766C4" src="cid:E7238746-2665-4298-A16E-CAC8E588F8F2"><br class=""><br class=""><br class=""><br class=""><br class=""><br class=""><img class="" apple-inline="yes" id="8FEA4621-BDA5-4BC1-85FE-D4BF47445A28" src="cid:16F407A2-EAD6-4A6D-B48C-D08FEC193955"><br class=""><br class="">Sent from my iPhone</div></div></div><br class=""></div></body></html>
