Bill, how about using a bulkhead fitting?  They are long on one side and short 
on the other.  Joe(B)

The wilwood master cylinder really really   _IS_  actually drilled for AN-3.
At the bottom of the hole is a standard 37 degree internal taper. They
supply an adapter with the master cylinder that converts it to 45 degree
double flare, but I prefer to use AN fittings because you can make them up
without leakage again and again. 
 
The ONLY problem is that they drilled and tapped it for the long fitting.
All AN fittings come in short and long, and the short is by far the more
common length. For the -3 the short length is 1/2" and the long is 5/8".
 
Actually, the thread for AN-3 is the same as standard 3/16 brake flare nuts.
The difference is how the bottom of the hole is finished. It's a REALLY good
idea for Willwod to do the hole in the aluminum master cylinder as an AN-3
because it's easy to make and it doesn't wear out like the raised nipple of
a flare fitting. My only problem is that I'm being finicky. I'll send some
pictures so you won't think I'm nuts.

Ok...your choice,but I've used the crush washers for many years with zero
prob,and thats with a full-prep F/P SCCA National car...As far as I
know,they don't make an AN ftg that goes into the MC threads.I believe the
end taper angles are different anyway.AN's are 37degs...and I think the MCs
are about 42ish...an acquaintance of mine is a brake system engr here in
Detroit and he had no problem with this set-up.
