Spicer 5789X u joints

If I understand you right, yur saying that with the cups off, the joint will not slip between the cup-holder saddles of the yoke; is that right?
Made in China?
Those guys just don't care; for them, it's all about money.

Just make sure the two saddles are parallel to eachother and that an imaginary bar passed through the cup-bores would find the holes in the same planes; the point is that I have seen guys press the cups in/out and bend the yoke.
I have seen certain yokes, not Mopars, with the saddles notched for clearance.
