Yeah, those are hatchet head detents....If I remember correctly, there are what...about 4 detents? Man it's been a long time....I think the very bottom and the very top ones are rounded on the ends....the middle two that sit in the shift rails are shaped like a hatchet to slide in and out of the notches on the shift rails easily.

Like I said, it's been a year or so since I went through mine....but that's the best I can remember....

I hope that's what you were referring to.....
