Lokar Kickdown adjustment

I have a Lokar kickdown cable in my '65 Barracuda, 318 w/ Edelbrock 1406 carb, cable shifted A904. It's never been adjusted correctly, I used to just leave a bit loose/ longer at the carb side, so it would shift when I wanted it to. Now I want to fix that and I read somewhere here that I might have to move the mounting point a bit more in on the lever on the transmission.

Since the transmission is in the car and it's not that easy to reach I was wondering if someone has done this and could possibly tell me where to drill the new hole. I would like to limit the trial and error to a minimum.

I heard there are a few different levers out there and who knows if this one is even originally from a '65 A904. currently the holes are 1-3/4" center to center from each other.

Any ideas?
