I have seen in other posts and on the CD a QRO11 or QRO12 quad ring. I cannot find these rings anywhere under those part#'s, Can anyone give me the dimensions of these rings or a place where i can purchase them. Thanks

http://www.mcmaster.com/ scroll down to "fastening and sealing" then click on orings down near the bottom of that listing. Next select 011 fo rthe dash nomber and then select double seal. There they are! Buy a bunch and give the extras to fellow XJer's or trade them for needed parts.
