I had to fit a centre joint because the alternator and oil filter were in the way. With three ujs I didn't want any play anywhere so I've used two of theses bearings with spacers turned up and tacked to the triangular shaft. I'm more than happy with it. No play at all.
I had to cut the original steering bush mount out and make a larger one and make up a 5mm bracket to carry the bottom bearing. I still need to chop a lump out of the engine mount.
