Thanks Dana.  I had previously visited the Mann site but couldn't get the
"online catalog" function to work.  Finally went over to the "Europe" site
and managed to figure out how to work the thing.  Here's what I found, in a
condensed fashion:

                Thread    Gasket Dimensions    Width
920/17    3/4-16UNF    62x4.5                 93
719/5        Same            Same                    76

                Height        bar*            R**
920/17        95            -                   -
719/5         123        2.5                1

*=Bypass Valve Opening Pressure
**=Check Valve

So, the 719/5 will spin on and seal properly on an air-cooled Vanagon.  It's
capacity is about 13% less than that of the 920/17, which doesn't strike me
as a big deal.  However, the 719/5 has a check valve and a bypass valve
where the 920/17 apparently does not.  Having a check valve and bypass valve
strikes me as A Good Thing.

So, I'll ask again:  Anybody think I'll have any problems using a 719/5
filter on my air-cooled Vanagons?

TIA.
