One broke at the pedal hole, the other further up toward the BB spindle but not all the way up. My memory of that one isn't reliable, it was 30+ years ago and I didn't keep the broken parts.

The following pic is not one of mine, just a pic I saved from the internet:

Mine broke off closer to the BB spindle. more like 15 mm from the spindle? Again, I don't remember for sure, sorry.
