Fred's was close, but it was for a three on the tree and not the auto. It was close, but wouldn't work. When I checked the new one and the old one side by side they appeared to be the same part, just a plastic indicator instead of the original that was part of the collar.
I have to work this weekend, so I may try for next week to pull it apart again and double check. Here is the three on the tree and the new auto one to show the differences. Unfortunately I didn't get a pic of the old and new side by side as I was sure they were the same. The auto is on the right and manual on the left.
