I think it would be ok with just bearings and a connecting rod.I also emailed ST and asked them if the parts were the same and they gave me a list of suppliers for replacement parts.They did that because of the disspute that split the company up I think.I thought the same that all of you are saying and I still think the parts are interchangeable.There's a LHS not too far from the one here where I live and this guy may have parts for it because he was a authorized service rep for several engine manufacturers.He keeps a large assortment of parts on hand.I have his number and I think I'll give him a call when he opens.Thanks anyway guys.
