Hi folks, this is kinda embarrassing, but does anyone know where I can pickup another left crank arm for a Shimano 2300 crankset? Apparently I didn't tighten my pedal tight enough and it stripped the shaft part where the pedal and crank are held together. It came off while I was riding. I just need the crank arm, 175 mm in length. Most stores don't carry left crank arms, much less 2300 crank sets in 175 mm lengths...

I have been calling around, they are telling me I would have to order the whole crank. If thats the case, should I upgrade? Can I just install a 105 or Tiagra crank in place of the 2300?
