I'll try to get an exact measurement tomorrow on my removed stock pulley. I'll post a picture like Andrew did if I can find the time in the evening, using the same style digital caliper.
Good to point out but isn't one of the belts just a spare though? My thought was to understand how many belts were used under the engine compartment at a given time and if one or both belts are off the shelf or special.
Thanks in advance for any measurements you can share. IMHO there is absolutely no need to post a fancy picture like that "proving" a number. If you're a contributing member here and you know how to zero and use a caliper, no one should question a simple distance measurement on a small part. Really - don't waste your time.
