I am looking to buy a new radiator cap for my 90. The cap currently on there is an AC Delco 17 psi., HC-44 with two ears on the side. It looks very old and the rubber is deteriorating. I see an AC Delco RC 81 on rock auto for sale. this RC 81 has a 15 psi rating and no ears on it for turning. Any suggestions? What s the best cap and rating to buy?
