This crank arm came from a 1970s Peugeot road bike that I recently parted out and is in good condition. It came off without any issues and the cotter pin is still in good shape. I don't have the other crank arm unfortunately. The pedal thread is good, pedals came out without any issues. There is no length stamp the crank arm but I measured it to be almost exactly between 170 and 175 so I'm assuming it's 172.5 (see last photo). Feel free to message me with any additional questions.
