Last time I broke a 4.11 R&P(reverse cut front) I bought a replacement set from Erik/Lucky8. Price was as good as any I could find at the time(maybe 2010?)
He also sent all the required bearings and crap(this was for an ARB front.
Since I broke mine, I think he is rebuilding diffs too if you want to go that route.
Hope that helps.
