8.8 swap yoke question

Spicer 2-2-1379 flange yoke will bolt to your existing round Explorer pinion flange, it takes a 1310 u-joint.

You could also replace your existing round flange yoke with a Powertrain Industries 3304-05 pinion yoke, which is a conventional u-bolt style yoke that fits a 1330/1330F (Spicer 5-7438x) u-joint. The 1330F side of that joint goes into the yoke, it uses a thicker 1330 bearing cap that resists being crushed out of shape by the u-bolt. The driveshaft side of the 1330/1330F u-joint is normal 1330.
