There's a whole big difference between "you can screw the Girling fittings
into a AN-3 fitting and if you crank down hard they don't leak" and "You
can mate Girling and AN-3 and they work really well together" The two
systems both use a 3/8" thread, and you can screw one into the other, but
that's the sum total of the interchangeability. If your TR-6 is a race
car, then get the Aeroquip catalog and order the correct fittings to
convert the Metric attachment on the caliper to AN-3, use proper braided
line with AN'3 hose-ends for the flex hose, and buy the correct hard-line
fittings to let you use an AN-3 termination on the end of the hardline on
the TR-6. The hard line termination uses a sleeve-nut and a bushing, must
be single-flared to 37 degrees, and will mate to the hose end on the end of
the flex line with a male - male adaptor. You may be able to buy a girling
to AN adaptor, too.
If the TR-6 is a road car, then the situation may need more thought, as the
AN- fittings and hose are not DOT approved, so you theoretically can't use
them on a road car. But whatever you do, don't just bung a Girling fitting
into a metric or AN hole. They may work for a while, but the odds are they
won't work for long.
