My pump has three holes with rubber grommets in them and the car has four holes that obviously don't line up. <HR></BLOCKQUOTE>

Some cars used a three hole pattern - others a four. I've got a '66 convertible and have the wrong pump as well (wrong # of grommets vs holes). I can take a look to be certain which one I have (not installed yet) and if I've got a four-grommet pump - I'd be willing to swap (I can take pics of the pump).

Anyway - the grommets sit in the holes - at least that's what i've been told.
