Yeah that belt was a bit of a pain for me to match as well. The one on it when I got it was definitely wrong, way too loose. Then I tried the parts store but their computer kept giving the ac belt for the alternator belt. Then tried to just match a v belt at the tractor supply but get it a bit smaller, kind of worked, but the v was too deep. Finally, ordered all the ones claiming alternator belt on rock auto and got 2/4 that fit and work correctly.
