I recently got the FC UDP and am trying to [hopefully] install it on my next day off. Does anyone know which serpentine belt i need? EscortFocus and NewEdgePerformance say it's a shorter belt, but their length varies from 1/2 inch to 1 1/2 inches. Anyone know a model number of a belt or exact size? And where I oculd pick one up from, and at about what price? Thanks!
