So my harmonic balancer just seemed to break off as if rotted and i need a new one. I asked a local engine builder and was having a hard time finding the harmonic balancer for my 72 mustang's 302 because of its depth and it being 4 bolt. so when he did find it, he found it for $140. this seemed a little pricey for something that wasnt aftermarket, just a plain jane one. anyone know where i can find one cheaper? or just go with that one?
