Have you tried kneesavers?
A machine shop should be able to make you something similar that will fit whatever threading your cranks/pedals require. Perhaps the cost would be greater than just buying an arm off eBay and bending it, not sure.

> Because I need to wear a brace on my left leg when I ride, I need more
clearance than a straight crank arm will allow. Thanks to Mark Stonich of B
ikesmith Design who bent a French crank arm for my old Chemineau, I am no

nd try to bend the left crank arm on it, or try to find another French cr
ank arm to bend? The original one on the bike is marked "Vedett France". I
don't want to spoil something original and irreplaceable, but I would lik
e to ride the bike.

ench threaded, however, I found out that the French pedals will screw o
nto the Italian or Taiwanese arms. I tried bending the one from Taiwan, b
ut, alas, it is very sturdy, (and heavy), and I could not bend it.
This left me with some Magistroni arms. I don't know if Magistronis are har
d to come by, and therefore should not be bent, so I need some advice.
The Magistronis are part of a set pulled off a Fiorelli tandem.
