So, I love the quality and pricing of VBELTGUYS v belts . However when I order it always takes a long time to sort through the search results . Usually I am after Sears - Craftsman replacements . There are .285 and .3125 belts, there is regular and Kevlar belts. There are 10 - 20 belts for the number Sear’s manual calls for. Then there is the offset between the outside measurement and the actual part number. Then there is the conversion between what part number I ordered and what I actually got. Then there are times when they are too short to fit , ones from another MFG are sent - and they fit !
