Last year our alternator belt snapped. It is a Gates Super-HC MN SPA975 Cogged belt, We have searched high and low for a replacement but with no luck, dimensions are (w)12.7x(d)10x(l)975mm. We have fitted a standard cut v-belt that didn't last very long. also an alternative cogged belt looking like it will snap at any moment although it has lasted up until now. I would like to replace this belt with what was on originally. Seeing the problem I'm having finding an alternator belt I would like to have a spare engine drive belt too, same type just shorter at 882mm. The Gates website is very hard to search.
