Not sure if 60 flange means Dana 60? If it is a 9 1/4" rear, the yoke interchanges with the 8 3/4". I would be reluctant to remove it as you may change the pinion preload as it may alter the crush sleeve. I have done it as a last resort.

If by small you mean 7260 joint and you want to mate with a 7290 a combination U-joint will work. Dana Spicer -5-527X part number crosses to an ACDelco 45U0169. This is a GM part, I just put one in our truck and it fit perfectly.

If it is a Dana and the 1300 series of joints, this too can easily be searched for a combination joint. Try some of the 4x4 aftermarket sites and there will be all types to get a good part number you could use at a local auto supply house.

If it is a Dana 60 rear axle (most likely is), then you can go to places like PartMike.com and get a 1350 yoke for it and increase the u-joint. You'll need to have your driveshaft end cut, have the proper size welded on and rebalanced. Since you want to go from a flange to a u-strap yoke, you're driveshaft length might change a little (probably not too much though).

As far as swapping them out and effecting the pinion bearing preload (or crushing the crucsh sleeve more - 9.25 has them, the Dana 60 uses shims), torque the pinion nut to 230-250 ft/lbs. and you'll be fine. It take more force than that to crush a crush sleeve. As for the shims, you won't crucsh them.

If you post up a picture of the rear axle, we can tell you want it is or take a look here - https://moparforums.com/forums/f76/a...801/#post64483

Go to Randy's Ring and Pinion and get you a 3/8" u-bolt rear yoke for 1350 u-joints and a 1350 slip yoke for the tranny and you will never see the sparks in the rear window like I did.
