Holley needle and seat O-ring???

Anyone have a part # or a size for the o-ring that goes on the needle and seat assembly on a Holley 4150 style carburetor? Some said it was a 008 o-ring so I bought some but they don't seem as thick or stand out of the groove as much as the factory o-rings. Looked all over and cannot find a Holley part # or spec. Holley sells them with the kit that has the hex,screw and gaskets but I can't find them separate.
