exhaust crossover fastener information

[schmoodog]

Hi,
I recently loosened the crossover header and misplaced the fasteners. I know there were 2 inches in length and partially threaded. Does anyone know where they can purchased and what the exact specifications maybe.

Thanks for reading my post.

I know they are metric, maybe #10 or #12. Not sure on the thread pitch. I have some at home in my nuts n bolts bins as it seems everytime I take a crossover down I wreck at least one of them.

They're defiantly metric. I can't recall the exact sizes off the top of my head.


I have to individually bag the X-over bolts on my SS ex bolt kits so they don't get mixed up with the SAE header fasteners.
