Thanks Brett for the BtDt!

A few things I ran into today...

That last booster nut on the upper left corner is hard
to remove but nearly impossible to put back on.  I'm
still trying......

The clevis pin clip shot off somewhere and I can't
seem to find it.... damn!, Can't drive it until I find
it or get a replacement.

There doesn't appear to be very many reports of failed
brake servos (booster) here or on the 200Q20v list.  I
did manage to find a thread from 11/94 but not much on
the topic in the archives.

Are these things usually fairly reliable?

back to work.
