I know there were some bad reveiws when this system initially came out, I'm not talking about the "locker" system, but the No-slip system. Some of the initial problems I have read had to do with the material not being hard enough. But now that this unit has been in production for a while, whats the concensus on them now for those who have converted their peg leg TR into a posi rearend? I'm thinking about doing this to my truck which uses the same part# as the TR's do.
