Harmonic Damper / Pulley Bolts Help

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

they are either 5/16 or 1/4 course thread , leaning toward 5/16 , 1/2" long .

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.

I have a couple dozen in the shed, cover the ride of 6$ and shoot me a mail addy.

I have a lots of engine bolts if you need others.

Lowes had exactly what I needed in grade 8. Thanks guys.
