Kombi c pillar seat belt hole help

[Bunty]

Hi guys, I have a t30 swb t6.1 which I’m putting a triple kombi seat in. I have all the brackets etc for the whole institution but I can’t remember where to drill the holes for the upper seat belts.
I have read a few threads but have seen different measurements and looks like the measurements are different from side to side!
Does anyone know the measurements? I presume they are the same height both sides.

thank you!

Are you fitting the triple in row 2 behind the drivers seat or row 3 in the cargo area?
