Can anyone let me know how to put new threads into a crank arm for the pedal. Both drive and non drive side have been stripped. I've got a tool from wiggle that can do it to a certain extent, but I think the hole is too big and worn out for these. I read about helicoil somewhere but not familiar with using these and what size coils would I need? Also I'm assuming I'd need to buy two of these for each side as the threads are different?
