The 1330 joint was used also. Make sure you confirm what you have, and what you need

It's me he's helping. I have a 489 case. 3.91 s.g. I have the 7260 U-joint. I want to swap a center section with a 741(or 2) case. 2.76 gears. For highway travel.( I haven't changed a u-joint in 30 years or so.)

I have been reading the rear axle tech....

Odds are pretty good that if it's a 741 case with those gears it's a 7260 joint, but never say never.

They also make adapter u-joints that are 7260 on one cross and 7290 on the other.
