I think your "wonky" applies here. I have use the standard screw with 35mm and 70mm bowl jaws.
I have an old set of powergrip jaws which came with a longer wormscrew, I don't believe they come with the jaws now.
Even with the longer screw it may be a push to use it with the new 75mm long nose. Without checking I think the powergrips are about 1-5/8 deep and the new longnose state 2" so???
