Difference between 7260 & 7290 u-joints

[440+6scamp]

I need to order a drive shaft and u-joints. How can I tell which u-joint I need for the axle yoke? Are the diameters different? The hole in my yoke measures a hair over 1".

Measure the inside dimension of the yoke, (between where the caps of the ujoint mounts) on the 8 3/4. The 7260 (2-1/8" yoke ID) and the 7290 (2-5/8" yoke ID).

The cap diameter for the 7260 is 1.078". The cap diameter for the 7290 is 1.126".

Perfect. 7260 it is. Thanks
