Peggy: I was wondering if any new head has the same bolt pattern as the old
Bryden heads?

It's unlikely that any will match exactly. The Jabsco manual will be the
closest match because the Bryden was a Canadian version of it, made
under a licensing agreement...but today's Jabsco toilets are nowhere
near the quality of the Bryden or even Jabsco toilets of that vintage.
They lasted decades...you'd be lucky to get 5 trouble-free years from
the current version.

So I wouldn't base a new toilet selection on matching the mounting bolt
holes, but on quality and durability within a price range that's a
little higher than $100. Fill the existing holes with epoxy or other
suitable filler and touch up with a little paint to match your gelcoat.
