When Fritz was originally looking for this part, I e-mailed
him a scan of the North American drawing for it. If these parts
truly aren't available from any source, I wouldn't mind making
up several ship-sets utilizing original parts as patterns (along
with the NAA drawing(s)).
Been down this path before with my project (no parts were
available, so I had to make my own out of 2024-O and
had them heat-treated by a local heat-treat facility).
I use the same local heat-treat place our shop uses (I work
for a major aerospace corporation building heavy/large
transport category aircraft).
Anyway, if there is demand for these parts (LH & RH) for the
T-6 project-base out there, the thought is to fabricate a form,
hammer up some parts out of annealed aluminum sheet & have
them profesionnally heat-treated to specification (I need
a pair for my project anyway).
Postcript: Forgot to add that making new parts from drawings
is one thing, but making new parts from good/straight patterns
in addition to the drawings is as easy as taking candy from
a baby...
