thanks gregory,
i'm looking into that and many other options. my understanding is that
i need a tap with the correct t.p.i. and diameter to receive the
helicoil, and a helicoil with the correct t.p.i. and diameter to
receive the pedal. i can't swing $100.00 to make this work, i need to
find someone local who has the setup to make it feasable.

ideally, a matching crank would solve everything rather quickly, and i
may just swap it out for another model crank and keep looking.
