I have an old F250 PU 1989 that has the 351 CID Cleavland engine and the harmonic balancer came apart. I need to find one, as my mechanic said it would be a dealer item or a junk yard item. He is going to ck as he works for a dealer but if i can find it it would be better. First major thing to happen in 24 years I got it with 6 miles on it, not to shabby.
