Blown rear end

It's kind of hard to tell in the pictures but looks like a single track I'm not seeing the clutch pack?

You're correct, first thing I thought: open diff, no big loss.

charlief1 has the answer, 30 spline axles and an Eaton posi to match. Be sure to replace the axle bearings and seals. New stuff for the punkin goes without saying...
