Phil, Are you certain that the late TR6 pipe is metric? I doubt that it is.
It is my understanding of the instructions is that the reason a metric
thread needs to be used is that the Toyota caliper inlet hole is metric and
therefore one needs to make up a special pipe using a metric one to start
with but cutting and fitting the end that attaches to the flex hose and
using the original female fitting.
The reference to metric in the instructions only refers to the size of the
caliper bolts and not to any of the threads.
To those who have done this modification am I correct or is it me who is
reading the instructions wrong?
