I'm not sure what others have done to make the the 8 rib not to stick out like it does ..it will tear up the belt..i did a lot of reading and no says what they do to make it fit ...i try-ed changing covers and that will not work they don't line up at all...i have try-ed all ways of moving it around with no luck it only goes in one way.... if someone knows how to make a 8 rib fit on a 6 rib alternator and have it line up ..please let me know... thank you
