Just to follow up on the pedals, this is the repair that I chose using the 
channel, flat strip and JB Weld.  I was able to use a few drops of the 
epoxy per pedal and "glue" the joints back together which made final 
assembly of pedal, channel, strip and JB Weld a simple chore.  Also,  I 
learned the pin at the rear of the pedal stem can be removed to allow 
sliding the repaired pedal in from the front then replaced when the pedal 
is closer to being in place.  It all worked perfectly and left the client 
in awe.  Thanks to everyone for their thoughts and ideas.
