Titan, I worked in a auto parts store for about 25 years, these u-joint's aren't hard to find, if you do lose some of the needles just take the old u-jount cross, and your old cups, they can measue, the cross and cups and fix you right up, if your real careful, even if you drop some needle, just put them back in the cup, make sure you have all of them, and put a little grease to help them hold, the old fibered wheel bearing grease, worked great for this, but that's long gone, hope this helps.
