Denny's Driveshafts offer a variety of Ford Mustang Universal Joints. The typical Mustang driveshaft was usually 1310 or 1330 series. Keep in mind that your Mustang may have any combination of u-joint sizes so please don't assume anything.
Please measure your u-joint width and cap diameter before ordering. The 1310 u-joint will measure 3.219 wide and the 1330 will measure 3.625 wide. Both will have a 1.062 bearing cap diameter and both use outside snap rings to hold the u-joint in place.
Ford Mustangs have used two different u-joint cap diameters at the rear end pinion yokes.... some are 1.062 and some are 1.125. Care must be taken to be sure to install the right rear universal joint.
Greaseable and non greaseable maintenance free versions are available. Our high mileage maintenance free Spicer universal joints are the best choice for long life and absolutely no greasy mess under that beautifully restored Mustang.
Denny's also carries the various Combination U-joints that allow you to connect mismatched driveline components.
