I broke an E clip for my Schatz 8 day cuckoo (small one that holds on the rack) and am trying to figure out what to order on Timesavers. Timesavers How do I figure out what to order? Timesavers has a bewildering list of choices here. The post on the front of the front plate that the rack goes on is about 2.5 mm in diameter and there is a groove cut into it to accept the E clip that is a tad smaller than that. The outside diameter of the circle on the front of the rack that the E clip fits into is about 5 mm in diameter. Thanks in advance for any help.
