Hi Rob, I think this thread could be of some help.

If you have any further questions, I will gladly try to answer them.

BTW, I have left all with original parts as it works fine in my case, but alternatively I have learned that Cain at Wolf Performance offers his own U joints and a very good alignment at the first joint after the steering rack, just in case. I have no relationship with WP, I am just a happy customer.
