I hope you didn't pay much for this crank. You can either find two replacement extractor rings and two compatible replacement crank bolts or replace both the surviving extractor ring and bolt with a new standard crank bolt and covers for both sides. A standard crank puller should be able to remove the crank arms in the future if you don't replace the autoextractor rings and bolts.
I didn’t pay much for the bike, it was an Estate Sale find and based on the amount of dust on it, it has been unused for a long time.
Thanks for the advice, much appreciated. I’ll need to decide on what to do. I like the idea of self-extracting cranks, but am perfectly ok with a more traditional system.
