Even more confusing for the thread is we are both Petes :)

I honestly don't know. Would you recommend keeping it and trying to get a drive to fit it, I would need to find another similar motor on ebay. Besides I am starting to hijack this poor guys thread here. I am open to whatever will be the best for the machine in the end and what is easiest for me to get running.
