Call them. I needed a replacement stud once, so I called them. They sent me a replacement free (gasp) and they next day airíd it to me.

if you measure one of the old ones you can look up the various washers they have in their catalog and find a match

I called, they told me ARP APW950-CP. from what Iíve seen while researching itís been hard to located. 7/16 chamfered on one side but the .950 has been the hard part to find. Most I see are 13/16 or something along that line.

Looks like they told me the 5/16 one when I needed a 7/16. The 5/16 one is .120 so Iím assuming Iím looking for a 7/16x.120x whatever the other number is

ARP lists their washers as ID ...7/16 you need....OD of washer....and thickness of washer

if it is a special washer to the kit...since they dont list a M11 washer ....seems they would be the only source
