Hi Guys,

I need a new set (6) harmonic damper bolts the ones that attach the crank pulley. Does anyone know the size and length? I just bought the damper below but Summit doesn't have a listing and didn't know when I called. I'm sure they are no different than stock but would like good ones like ARP if possible. Or comparable something that you may suggest. Thanks

5/16 by about 3/4 coarse thread will work. Would find a Mac's and get grade 8's.

Thanks what do you think about using stainless? I wanted to use something that wouldn't rust.
