Hard to see in the picture, but looks like the o-rings have nothing to
seat on in part of the holes.

Indeed.  I'm making a gasket instead.

However, I may yet be able to provide a surface for the
o-ring.  The present cutout is undersized.  At the time,
I only had a 3/4" end mill for cutting it, but it's
supposed to be 2.0cm.  I put in an order for the correct
size cutter with Rutland.  If I'm very careful, I think I
can leave a 2mm seating surface all the way around.  If
not, the gasket will work every bit as well.

BTW, Racing Beat or Mazdatrix sells these.

Yes, and after I get the bugs worked out of the production
process, there'll be a third source.

As I mentioned in an earlier message, I'm almost done with
one that offers two threaded bosses for sensors or remote
feeds.  If someone wants one with three bosses, I can do
that, too.  I have to be out-of-town next week, but I
should have more stuff to display after Christmas.
