Need to locate a replacement rear universl joint For a 92 4WD F150.

Looking for the u joint for the rear of the rear drive shaft. It measures about 3.5 inches across from outside of cap to outside of cap. All the ones the parts stores have are 3.622 across and I cant get the locking clips in place.

Called the dealership and they don't even have the right size u joint. Everything appears stock on this truck too. I'm pulling my hair out on this one! Figured this would be an easy fix.

 

The next smaller size width is the 1310 series. Width = 3.2 inches.
The link below has the dimensions.
