I dont know what to tell you on the carrier bearing....they are all pretty universal. Generally the only options yiu have when buying a master install kit is v6 or 4cyl, there are no ratio / year breaks thar I can think of, atleast in the pre tacoma mini trucks.
The only thing that pops to mind is maybe the new third you bought is for a tacoma 8.4 axle....they are slightly larger and will not fit in the older 8" housing.
and universal for bearings i can only find 2 differnt ones
i will try to fit it in the housing tonight
