U-Joint

[ford_munky_man]

Ok, some of you may know my problem with the rear u-joint on the rear driveshaft. The cups that attach to the yoke of the rear pig are too small. So does any one know what size of joint for the driveshaft of the 100? And then the one on the 250? I was reading somewhere that you can go to a driveshaft shop and get a hybrid u-joint that has the two sizes in the same joint. How much would this cost, if anyone knows.

The first thing you need to figure out is what size yokes you have.

1310 series U-joints are about 3-1/4" across with a cap size of 1-1/16" or 1-1/8"

1330 series U-joints are about 3-5/8" across with a cap size of 1-1/16" or 1-1/8"

1350 series U-joints are about 3-5/8" across with a cap size of 1-3/16"

Both of your yokes could be 1310s with different size caps.

NAPA will sell you a hybrid U-joint if you know what size your yokes are.

I know Advance Auto Parts carries Conversion Joints in stock and they have a chart. They are specially made for things like this. Like Digger said, Napa should be able to get a handle on it too.
