I would bring the proper ones (r066030) to an automotive store & let them get you a properly sized one. Crusader belts are made by another OEM under contract so just buy one of good quality, ie not the cheapest one! My engine uses V-belts, but I just took my old ones to Napa & they got me same sized replacements. Been using them for a few years now with no problems.
