Just a bit of info, i just completed a motor swap from a 25hp kawasaki carb motor to the 810 vanguard on a hustler Z. The Vanguards are on ebay for 1199, older assembly date, but are legit and New in box. The most difficult part was simply tig welding the exhaust to do the cross exhaust vs dual input that came from the factory. I plugged the new exhaust and did a single input in. On the hustler z's the vtwin is sideways. The throttle cable hooks up the same as stock, honestly works better...
