Trying to source an LSD for my U61T, from my research U61/62T/W/V Minicab/Town box and U71/72T/W/V Nissan Clipper are the same but they seem to be hard to come by even on yahoo japan auctions. Tried amayama for a new oem one and dont fancy paying $1500 for a new or aftermarket center. Does anyone know if the diffs are shared with other brands/older models? I'm happy to import another open diff and swap another center section into the minicab ring gear.
Have you considered Traction Concepts conversion as an option? I actually bought on only to discover that I didn't need it. Kind of embarrassing really. https://www.tractionconcepts.com/Mitsubishi-MIni-Cab-U62T-V5M11-LSD-Kit-p/tcxmi7741.htm
I did see the traction concept kit but I'm skeptical that it'd provide anywhere near the locking capability of a multi plate clutch type lsd. I might import another open diff and do some measuring of the housing bolt pattern and axle splines to see if anything else will work.
