Thanks all. It looks like #9 or #2 from the link by mobeewan. It is under the body of the PleasureWay and I can only get to it on my back. The horizontal 'flipper' on top is what broke off and the vise grip grabs to the vertical stem at the bottom so I can turn it. Not sure if it's the screw in type or the punch in type until I get it out of storage. Sounds like the Screw in type is preferred and something I can work with. The punch in type would expand the hole as I pull out, then it would leak unless I replace it with a slightly larger diameter screw in type. Thanks again everyone. Sounds like it might be worth the effort.
