WTB: 8.8 31 spline LSD carrier or rear end

[thomasdale2144]

Hey guys I've got a 1988 F-150 with a 8.8 31 spline 2.73 geared rear end and I'm looking for a carrier with a LSD in it or a 8.8 rear end with an LSD. I don't know much about the differentials on these trucks so any advise would also be welcomed! Thanks in advance!
