No but the sure grip unit can go into either one the center sections.

Believe it or not guys but a few yrs. ago I bought a 489 3rd member assy. from a guy and when I pulled it apart it had 741 gears in it. I thought it couldn't be done but aparently if you use the correct bearings they can be adapted. When I saw it could be done I investigated into whether or not 741 or 489 gear sets could be swapped into a 742 case and also looked to see if 742 gears could be used in a 489 or 741 case and couldn't come up with bearings that'd do the trick for either. Your better off using the correct gears any time but if you have a 741 gear set and can figure out what bearings it takes they can be used in a 489 case. Wish I'd have wrote down what they were but I didn't.
.......Ive had a couple 489 cases with 742 gears in them.............kim......

No kidding... I tried to figure out what bearings it'd take to do that but came up dry... Somebody must have figured it out...
