Axle code says THC which should be a non- posi 3:73. At present I'm sure about the lack of a LSD but the ratio is a mystery. Not that it matters as the plan is to swap my newer internals into this housing..
The cover is all goobered up with silicone so someone has been inside it. The center housing had a good 3/16 or more of greasy dirt on it which I'm pretty sure is from the top part of the cover. I flipped the axle vertical on the jack stands oil dripped out. A clue even I can pickup on.  The oil even looked nice and clean. 
So after several hours of cleaning it is just about ready for some paint. |
Yes, stock would have been a 3.73 ratio open . Looks good.
