i've not been able to find the segmented v belts without having to buy a lot more than I actually need, just to make sure the 18 is going to run. The 18 does have the nose plate beneath the radiator, so I may be able rest the radiator on it in order to get the new belts looped around the harmonic balancer-crankshaft sheave. Would sure like to find 5-6 ft. of C section segmented belt.
