I see this thread is essentially done, but can't resist making a comment. I'm retired and doing a little consulting as it comes along. 50% of the answers I provide supposedly from my many years of experience can be found by just googling the question. It's like stealing, only legal. Same for OP's question here. All he had to do was google "Italian octalink bottom bracket" and a ton of sources fill up the screen. First three sources for anything you need for a bike no matter the age or how esoteric: Amazon, ebay, and/or Google. What is so hard?
