Procharger Harmonic Balancer Bolt Length
For the guys on here running a Procharger, what length bolt are you guys using for the harmonic balancer bolt? I just broke my old one and am replacing it with a new one. The ARP bolt that I got is 2-3/16" long. When I thread it in though, it only engages the threads about 1/4 to 3/8ths of an inch. This just doesnt seem to be enough engagement to me. Should I just buy a longer regular grade 8 bolt?

You could use this

or this is a bit longer, but smaller head size

I believe that first one is the one that I am using now. Thanks for the link on that second one.
