Update, I have bad news. The coupler and the tail shaft of the main trans mission are stripped. I plan on getting cryogenic treated parts from Midwest Transmissions. $600 in parts. But then instead of 475 lb-tq I can do 613 lb-tq. So it sits for now. On the other hand I went ahead and installed the new electric fans from Flex-a-lite. never gets hot now. Also installed front receiver hitch.
