I bought a set of ARP head studs from a friend on here, one of the studs is missing a washer and a nut. I did about two hours of digging and searching many different things. I'm asking if anyone knows the specs to the nut and the size of the washer. I found a site that sells replacements but there's so many different size nuts and washers so far I found out its 7/16 but I need much more than that. Thanks for any help.

 

Bump.

 

You are going to have to call ARP or spec them yourself.

 

Well worth the investment. I love my sets

 

Yeah I will have to do that then, thanks!
