Roy - Glad to see you come back and post.

Looks like you need to go a fair distance to get to a well known name brand auto parts place like O'Reilly's or Auto Zone in your neck of the woods.

Either of those sources should have or be able to get a 235 water pump gasket. Otto is correct about finding them at rockauto.com, but before we can suggest more, what year 235 are you trying to work on???
