Hi, I have a 1990 buick centry v-6 3.3,, I can not find the correct harmonic balancer for it, neither can that auto part stores or the dealer. mine is 7"dia and about 1.5" thick everyone is trying to sell me a 3'thick . I tried one and would need to purchase new bolt and fins dont reach crank sensor anyway. what do I do? I cant even tell what year engine is? maybe that is the problem.
