|My project is complete. I procured a new lower u joint from Martin Robey. Just getting the part was the hardest task, as I could not complete the transaction with their web page and it took half a dozen calls to complete the purchase by phone. About $64 US and arrived in less than a week. Expect some American English/English English communication difficulties.
Replacing the lower u joint and the fire wall bushing took about 2 hours. Short test drive felt tight. looking forward to a longer drive.
Thanks to all for the comments.
