I'm switching to 31 spline axles so I can some more common diffs w/stock case instead of my current spool. Bought new less than a year ago. Complete with 1/2 long studs, bearings and Big early retainer plates. Ran with stock '03 5.3 and stock truck torque convertor. $400 OBO + Shipping. Text me at 417-300-1013 if interested
