Cam Color vs Number of Teeth

A home owner from Sterling, VA says:
I have windows of unknown manufacture, and the tilt-lock shoes have shattered (where the balance hooks in). They have a TEAL cam (like #15-015) but have 3 teeth (like #15-118). Which one is more important. Size is too close to measure.

What is the balance series?
Is there another window in the house that uses the same pivot shoe?
If yes, please include a detailed photo with your reply.

Balances are 600 series 37"x5/8" Red.

Here is the old Pivot Shoe from my windows, which should be the replacement? It's approximately 1 1/4"x 2" x 1/2", though these are not exact. I have narrowed it down to #15-015 (Teal Cam, 2 teeth), #15-046 (White Cam, 3 teeth), and #15-118 (Blue Cam, 3 teeth).

Update: It appears my old shoes are 17/32" thick, which you guys only have with Teal Cam, will this work?

On repairing vinyl windows I would recommend the 15-046 . Reason being that the break shoe is in the back of the shoe similar to your photo. The 15-015 is used primarily with the aluminum windows it has a side break shoe. The 15-118 shoe could be a little too thick for your track.
