tf-2 shift kit

ahs anyone ran into where the kit states to drill the hole "r" if not there, and then it states to remove reverse check ball and states install ball on channel plate were hole "r" was drilled? this is the last of it and i"m confused... I will be running a higher that stock converter# 2200-2400 rpm.. please see pics.... it is a 1973 trans... and if I relocate ball to new drilled "r" which ball to use. the omitted #2 smaller one, or the reverse larger one?

I see nowhere in the instructions that it states to drill hole "R" if it isn't there. Your plate doesn't have hole "R" so you don't have to do any mod there. That means don't drill anything and don't put a ball in it
