The groove won't be uniform depth if a beveled ring/clip is called for. The groove would require a matching chamfer/bevel and is the reason a specific orientation is called for. I can find no cross-reference to see if the TCM ring P/N is beveled. Non-bevel rings normally use a uniform groove.
I believe the line you refer to is part of the weight itself as shown in SB picture. The pin is not that wide.
