what you are saying is the carrier bearings and races are the same in the two defrent carriers 741 sg and 489 open ?

The outer diameter of the races are the same. The bearings might be different depending on what year (different i.d. on some yrs.) but it doesn't matter if you just keep the races from the sure-grip with it like Rob said.
