    Am trying to identify a GM 10-bolt rear end. It is stamped on the axle tube: 2FE 0 152 and stamped on the center housing: 555771.

    If this helps, 10 Bolts are pretty much the same except for spring perches, (coil vs leaf), and widths. Some 10 Bolts had the same size Pinion shaft Dia. as 12 Bolts, which is very desirable, but any 10 Bolt could be upgraded to the heavier Pinion Set, same as adding Posi. Ratios are indicated on a cover Tag and Gears.... Some newer 10 Bolts have Disc Brakes.
