I'm trying to figure out what o-ring set I need for the oil filter adapter on my '91 Cherokee. It has the 5/8 bolt head on it, not a torx or allen head. I've heard of a lot of places even dealerships giving the wrong size o-rings out.
Does anyone know the mopar part number from the dealership or what size rings I need for my '91 oil filter adapter?

 

just take them into Napa, have them match the sizes,thats what I did
