I bought a set of used ARP head studs for 97-03 LS1's for a great deal, but one of the large washers is missing. Is there a place other than ARP that I can get that particular washer at? The ID is beveled on one side, so it's not exactly a standard washer... Or... does anybody have an extra one?

 

Try calling ARP (800)826-3035 or (805)339-2200, it couldn't hurt.

 

Bump... Anyone else?

 

You don't post a location, but an industrial supply house would have something close (just take one with you for them to match). You don't need the bevel with studs, only with bolts. ARP just sends the same washers with both...

 

Summit Racing has them ,Just call them and tell the what the O.D. of the stud and what they fit and thay will fix you right up.

 

Thanks. I just called them for the part number for the large washers and a technician was able to help me out. Here are the part numbers:
ARP 200-8512 (Each)
ARP 200-8522 (Two)
ARP 200-8532 (Ten)
