valve cover washers question

[painsinner]

Hi folks,
I am searching for those triangular washers for the valve cover bolts, some of you have installed. Any part number, inet-shop available for me?
Thx Stephan

You can get the chrome ones aftermarket at any Autozone

I think those are captive washers that are built onto the bolt.
