What u-joint does the 9 inch need?

I think I need to get the 1310 to 1330 converson u-joint for my driveshaft but just wanted to make sure. The 9 inch is 1330 right?

They can vary based on the year, measure the cross length to know for sure.

It should take a 1330 joint. You also need to measure the u-joint cap diameter since the 9" used two different sizes. One was 1-1/16" and the other was 1-1/8". I believe the 1-1/16" cap was more common and is the more common conversion u-joint found at the auto parts stores. The conversion joint with the 1-1/8" 1330 caps is harder to find, which is what I have. If you need the part number for it I can check when I get home, but if I recall it was a Neapco brand u-joint. When I get a new driveshaft I am going to run a 1330 joint at the pinion end so I don't have to mess with the conversion joints anymore.
