Max,I don't know what part of the world you are from,but here are a couple of places in Illinois that are doing it:Ag Machine Solutions,Virden,Il.[217]971-6532 model 920-$1700.Or try Marshall Ent. near McNabb,Il. phone-IJ price is similar.My neighbor converted his own 918 from a list of parts and advice from a friend.Keep looking around,there is a market for this conversion,so somebody should be offering it.Maybe one of these places would sell just the plans and parts list.Good luck.
