[urq] Brake servo leakage

[n-engelbert at terrans.net]

So, priscilla's brake servo is leaking, bad, steering groaning a day after
refilling the reservoir bad, big puddle on garage floor after 24 hours
bad, which seems to be the failure mode of the part from what I've read.
Also from what I've read about these, they're made of an isotope of near
unobtanium.  The leak is coming from the front of the servo where it mates
to the MC.  The seal between the two looks to just be metal on metal?  Is
there a gasket in there that I'm not seeing either on the car or in the
family album?  Part number?  Do they all fail there?  Is it safe to make a
gasket for this connection as I assume it sees bomb pressures?  Does sport
wheels out in colorado still rebuild these?  Should fluid be against the
connection between the BS and MC or is the BS leaking from an inside seal
that should allow no fluid to contact the MC?  Good source on a new one,
from searching I see Pete Reeve at the Quattro Corner, others?

Help!
