Are you saying you bought the rear end on the basis that it's rare.. there are alot of rare items and i can tell you why they are mostly rare.. LOL
and correct me if i'm wrong but you bought that FPR from car mate yes.. which isnt rare.. they just keep molding new ones.. not like an optional kit from nissan that wasnt really chosen so there aint many out there and nissan charge through the roof to purchase a GENUINE one
