I think this issue was discussed a few years ago, (maybe on a
Commuta-Car website though).
IIRC someone suggested contacting motor repair house, and asking then to
slice off a piece of the proper material (you don't need much).
Many shops keep a slab of it in stock to make custom shapes for various
motors.
I did this & gave them some money for their time.
The material I got is reddish brown in color, about 1/2" thick, and upon
close inspection, has layers of woven fabric at its core.
It is very tough !
Basically, it looks like extremely thick FR4 circuit board, but brown
instead of off white (or the green stuff most people have seen, due to
solder mask color).
Very easy to cut with hack saw / band saw. & easy to drill for the
terminal stud to go through.
Usually need to do some shaping to make sure it locks into the square
(or round) hole in the wall of your motor - and keeps that connector
stud centered.
And, you make something for both inner & outer sides of motor shell - to
keep wire terminals away from metal motor shell.
Best of luck,
John
