there are two different sizes, 3.622 and 3.219 outside lockup. No rhyme or reason why you would have one over the other.
I picked up a pair of the 3.622 figuring the larger one was for the diesel, but was wrong and had to make another trip to the parts store. They do make greasable u-joints in these sizes. readily available on this side of the pond.
