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?
