ARH headers collector bolts

[Arizona Vipers]

Does anyone know the dimensions of the bolts that bolt the bottom of the headers to the collector?
I am trying to get these installed and the bolts were missing from the box. I need asap so will just go down to a nut and bolt shop as soon as I know the dimensions.


Thanks!

They are 3/8" but two different lengths. 1" and 3/4" I just measured mine. I would take the lower in with you to the bolt shop just so you are 100%.

I just assumed they would be metric but they aren't. They are 12 point head also if that matters.
