Sure grip question

Good thing is that clutch Dana center works in all the 3 cases. Don’t do what I did and put a cone unit in a 742 case. Worked fine with 4.56 gears but when dropping to 3.55 not so good. Pinion rubbed the center. Had to shave the pinion head to get it right. All because I misplaced the buttons at some point and used a cone center to move forward. Sold the Dana center long ago but have found the buttons and still have them.
