Chevy 10 bolt ID?

I have a 10 bolt and cannot find any info on it. I want to convert to disc's but need to know what it is. The numbers on the drivers side of the pumpkin are 3725899 2163 and a T8. On the passenger side it has BB 0927. There are no markings on the axle housing that I can find. It also un bolts from the front not the back. All the 10 or 12 bolts that I have been seeing dump from the back, so I would assume i is a early 10 bolt. Can anyone point me in the right direction?

can you post some pics of it? mounting pads, housing ends, etc

Sounds like you have a 55-64 Chevrolet rearend.

More specifically 1960 Chevrolet

It doesn't have any dog ears coming off the hogs head. It's in a 23 t bucket and it has had braces welded on it. Im pretty sure the rear has been modified for use with the 23.
