If I were you, I’d contact ARP. They have great customer service.

I was told a part number that they don’t even have in their catalogs or online

Call them. I needed a replacement stud once, so I called them. They sent me a replacement free (gasp) and they next day air’d 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 I’ve seen while researching it’s 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 I’m assuming I’m 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
