Measuring for Alernator and AC compressor belts. Noticed that the Ford Ranger and Mustang 2. Belt width of , 13/32 inch 10mm belt fits well in the crankshaft and water pump pulley. Top slightly proud of pulley. 1/2 inch 12.5/13mm belt rides above pulley. Does not fit into pulley. The Sanden AC compressor and Alternator do not appear to be an issue at this time. Both belt widths fit inside of pulley. What is the correct width, "Vee" belt? Width not length. There are several widths available. My local parts jobber was laughing, told me, "rarely sells "Vee" belts anymore. Thanks in advance. Steve V.
