I don't have the directions, you do.:D
FIRST let me say that since the 3/8 ball and spring pocket already has a hole drilled, that VB has already been modified/or kitted.
The holes in the separator plate have probably already been drilled also.
Look at what the instructions say for each hole and it's size options and compare that to the holes that are there already.
Then see if you need to drill them.
On drilling the wall, that means one of the walls between fluid channels like where the red dot is in this pic.
Drilling that wall is the highest firmness option and will make some really hard shifts if I remember correctly, but make damn sure you want that and that that's where you are supposed to drill.
If a wall is to be drilled there is usally a metal plate in the kit with three holes in it.
The two end holes are where you screw the plate down on the valve body, and the third hole is the drill guide.
Then you drill straight down through the wall creating a gap in the wall.
Did your kit come with that flat plate?
