I have a old Open Road 12 speed 4000 GTX and my pedal came off. The crank arm is stripped smooth so I want to get a new one but I can't find any. Probably cause it really old. It says Shimano Selecta 170 on it. Is there any other arm I can buy to replace this one?

If you want to go cheap... try to find an old shimano 105 or 600 arabesque... follow the link, probably u wont need to change the bb axle either.

If you really want to try and keep it all original, you could probably have a heli-coil put in the crank arm. There are many opinions on doing that, so do a forum search here and have a read. Any decent machine shop can install one if you decide to go that way.
