Auburn or Eaton???
What posi unit do you all recommend for mild abuse in a C3, Auburn, Eaton, or stick with the OE? I'm considering a new posi since everything is disassembled. I don't have big horsepower numbers but it runs quick and has broken a u-joint, an axle and stripped part of a ring gear. All suggestions are welcomed!

I'm not sure which one is conical, but the conical style may not be rebuildable. Something you may want to consider when shopping ;) .

The factory rear is an Eaton. The Auburn is a light-duty cone clutch differential. It's O.K. for everyday street driving but if you're making good power, have good traction and like to "use" the car, the Auburn will not last long. The Auburn is cheaper, though.
I would just get the stock rear tuned up with a rebuild. Unless there are problems with the case (cracking, pinion shaft holes wallowed out, burned bearing surfaces) there is nothing to gain by replacing the thing.
