Im re-assembling my exhaust system.  I have a 2.2L subaru engine with custom exhaust header, but I am stock vanagon from the J pipe downstream on a 91 Vanagon.
 
My bently shows 5 special washers where the J pipe joins the header.  The PO did not have those in there.  My exhaust header was quite badly cracked.  Now that I am putting it back together i'd like to include them - I assume they are there for a reason.  Can anyone give me a part number or better yet a size/description and I can get them from fastenall.
 
Thanks
