Lord, what a hellish mess! (I thought I had problems when I discovered Raul needed a ring job). Would I be correct in guessing that your fragged main bearing wasn't a Superblend (#NJ306E -- the pre-Superblend bearing doesn't have the "E"). These weren't stock until late '72, so your bike didn't have them originally, and a pre-Combat engine might have lasted 'till now without them.
If you find the bearings aren't Superblends, replace them both, (however good the other one looks), and don't let anyone talk you into anything other than the genuine FAG bearing, #NJ306E.
If you find that the failed bearing WAS a Superblend, I'm not sure I want to know about it. They're supposed to last 100,000 miles, and I still have 90 K to go.
