Darned if I know how I wound up with the brace on mine -- the facts are
lost somewhere in my now-murky past. I know I wasn't surprised to find it,
so at some time or another I saw one and thought I was supposed to have one.
AFAIK before getting under the coach, there's only one place to measure --
from the hole in the bracket to the threaded hole in the FD. Question is,
do you have the hole in the FD?
As far as the profile of the brace, it's basically straight except for the
90* bend at the bracket end. It's not flat stock but stamped to provide
greater rigidity with thinner material. I'd probably use 1/4" bar stock if
I were making one (though 1/8" might be enough).
I'll get to the shop after breakfast.
