thank you both and yeah they are old style. ive been doing some research and i found a couple of posts saying that they switched over sometime during 93. my car mustve been made before then. im kind of pissed though because when i was buying those o rings they said for all 93+ na models. i didnt even think about checking it. if the o rings that are in there now look good and i wasnt having any problems with them leaking (changing them was more preventative maintenance) are they still okay to use? i would assume so but it would be nice for another opinion
