I had O rings so I just decided to buy some 1 7/8" C clips I got at lowes and bend them out a bit to fit the HKS (which requires 2.25" I think). They seal tight, whether they will be enough I don't know. When I get my car running I will see. If they don't seal properly then I'll go ahead and order them from that guy. 10.87 canadian isn't much, I don't think.
