Make your 20v a 20vt...

Ah...OK...

I didn't go downstairs and check the 351B sitting on the shelf.  I just went
by the fishy, which showed a triangular gasket w/3 bolt holes on the 351N and
a 2 bolt hole version on the 351B (should have checked the part number, as it
is the same for that seal).  That should make things easier to set up for
machining...

The o-rings sound like typical rubber o-rings that get compressed by the
parts, while being held capitve in a groove.  Maybe I'm trying to over
simplify it?
