Super Jet Need help finding this gasket

[kawa js550]

Need to repalce this gasket but all I can find is this one http://www.ebay.com/itm/191517044996?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT. Is this the right gasket? Im not sure if it is because there is no holes in the gasket for the cooling ports to pass through.
