I am in the process of replacing these on my car too. I am guessing the reason for the above note about the cap side being towards the tranny does indicate a clearance problem like both you and cboggess alluded to in the two threads? Man it would be so simple if you could just reuse the same oem shoulder bolt/nut combo found in the other half of the joint. I wonder if they had reversed the drill order if it would have worked that way(larger opening in the fork on the tranny side instead of the smaller)? Then you would only need clearance for the head of the shoulder bolt.
Its over two years down the road, how are the nylon bushings holding up?
