Found this in my dads garage. Im pretty sure its a chrysler diff considering that all he had or would have. The spider gears dont turn and im confused with the TRAC-LOC. Please give me some info.

On the side it says 73494-x, 11-16-94,4275. Its got 12 ring gear bolts and it measure just 8 11/16 from outside to outside where the ring gear bolts to.
 
Dana 60, 4.10/down Trac Lok case. 1.31", 30 spline axle.
 
what do you think it is worth?
I just bought one for $130 on Ebay, then couldn't use the darn thing :angry5:. I was going to install it in the front of my '98 Cummins, but I recently swapped in '01 axles and the shafts are now 1.5", 32 spline. I didn't figure that out until a few days before the gear swap I was doing. I also put a Power-Lok in the rear. I thought about ordering the 32 spline side gears for my diff., but that was another $225 or so and that was NOT going to happen. You might check to make sure it is still 30 spline.
 
How did you decode this?

A BUNCH of searching through the Dana website and a couple of parts manuals I have. I knew it looked like the one I just bought and was probably for a Dana axle. 73494X is actually the part number, 11-16-94 is the date of manufacture so I assumed it was in a 1995 model vehicle, which helped track it down.
