harmonic balancer bolt

What about a hardened washer? Anybody sell a good one? Whomever put on my balancer probably used the bolt to try to pull in the balancer onto the crank - it is a very tight fit - and chewed up the washer in the process. I will heat the balancer to expand it so it will fit on correctly when it goes back together.

Arp is what I've always used and they have never let me down.
