coil balance replacement part, cam
I'm afraid the 15-215 is only made one way. I don't know of any alternative design that has a different style cam.
Before I recommend anything, can you please show me a photo of the pivot bar?
Thank you! That would definitely explain it. Your old pivot bar is a little too big to be compatible with our 15-215. This pivot shoe is meant to work with pivot bars like our 26-398 and 26-405, whose tips are much skinnier than what you show here.
You could consider one of those products as a replacement, depending on hole spacing. You may also want to check to confirm that the 15-215 was, in fact, the right part to replace your old pivot shoe.
