Just wondering if anyone had a list of what Warn winches will fit in the ARB Bull Bar. It says most will fit but which will and which will not. Also a friend is telling me to go with the 9.5ti or 9.5si M.O.S.F.E.T. and I don't know anything about either other than they are expensive. Finally can anyone explain what the M.O.S.F.E.T. does in plain english?
