489-741-742 in order from Left to Right (just put a solid sleeve on the 489 and you'll never have any problems).

thats exactly my point... see how the 741 is straight with no step? yes the 489 and 742 have a bigger pinion but they all run the SAME YOKE... which means effectively THEY ALL HAVE THE SAME SIZE PINION... dosn't matter if its 4" in diameter by the head... that step is the weakest link...
