D4B DC mods like the LD340 DC mods?

I think the notch on the one in pic is original? All the ones I've seen have that, or divider is milled down.
I put this one on my H-code Duster. Should I repair the center?

Edit: that might be one I sold. I had 2 of them at one point. I’ll have to check now!

Leave it. You won't know the difference.
