Tim,I havent ran my motor yet ,but my conversion is done and was pretty easy.
I used the Moss fan eliminator kit with thin belt.Didnt neeed to change 40A Kubota($69 ebay)alternator pulley.Some small mod to pedastal mount and it fit right in using stock adjsument arm.I had to cut away Rt. hand drive streering box mount. About $310 for everything,including new belt.
