competetion plus question

Hi all, I have a competetion plus shifter that came out of my B body. I just rebuilt it and am ready to install it. While it was a apart, I noticed there is no hole in the reverse "arm" for the neutral pin( to aid in adjusting the shift rods). The 1/2 and 3/4 both have the hole, but not R. I can simply eye it up, or drill it, but I am trying to understand why no hole for the R arm?
Has anyone ever seen this? I don't think this is an original Mopar/Hurst unit. I think it is an aftermarket Hurst.

Thank you

Rich
