Rear drives haft U joint too small
I am trying to replace my rear drive shaft U joint at the axle. I stopped by Autozone and grabbed what I thought I needed, only to discover that it was about 1/2" too narrow for both the drive shaft and the pinion yoke. After then going to O'Reilly and having them sell me another too small U joint, I've measured and discovered it to be a 3.625" x 1.0625" joint, equivalent to the Dana Spicer 1330. However, it has the outside lockup spring clips (as opposed to the inside lockup c-clips). Any idea what the off-the-shelf equivalent to this joint might be, and why I'm having such difficulty finding it?
