RE: cv 12 mounted on lmh 117
All,
I was just looking at ebay and there is a few 12s there for some great prices. They may be worth looking at if you are thinking about trying a conversion.
look under car, engine. (at least one is a new pull-start). These may not be the short shaft that I used but you may be able to come up with a way to use the long shaft type.
