I have gone through a few harmonic damper pullers now and am increasingly frustrated. The first set bent ( not surprised - Chinese). Second set was Sears professional brand.. but it did not have the 5/16-24 TPI bolts. Shopping for bolts, I could only find grade 5. NAPA did not have them either. ARP offers in Grade8 + but they are now on backorder.

Is there a Harmonic balancer puller /installer kit available on the web with grade 8 5/16-24 bolts of at least 2 inches long ?
