NEUTRAL SAFETY - Does anyone know

I'm disassembling my console shifter mechanism on my 69 cuda. I need to install a neutral safety switch on the shifter because I'm putting a GM 2004r tranny in the car and won't be able to use the original 904 tranny switch. When I took the console apart I found that the shifter has these two threaded holes right where a neutral safety switch would be located. Did Mopar use a switch mounted on the shifter on other cars that used this shifter mechanism??? Could I use a Mopar neutral safety switch on this shifter without making the modifications that I am planning on doing?? You can see the mocked up switch location I plan to use (white piece of cardboard). I was planning on buying a small push button type switch and let the shifter run into it as you go to park but no need if Mopar makes one for this shifter already.

Thanks,
