Thank you for the offer, but I just burned $25 worth of Amazon cash-back points to get a replacement. They will be getting replaced, for sure, but I need the car running and a complete set for sale or use on a milder engine later.

I know that to be the case, but it has always been for oiling reasons, getting the right heighth to get oil into the cup. the ball and cup show no signs of distress. I am really starting to think it shifted sideways and moved the oil groove out of alignment with the hole in the shaft...
