A conversion from a 650 or 700 to a 1000cc prowler can be done, just ask 1PhatCat. Unfortunately it is quite extensive and much easier and cheaper to just sell ur 659 and buy a 1000. The setups are completely different, 650 clutches are on drivers side of engine, 1000 clutches are on passengers side. Plus the diff's rotate opposite from a 650 to 1000. I could be wrong but if you want info I'd search and ask 1PhatCat. Good luck.
