Vy commodore power steering

[Robbo14]

Hey guys new to this place, I have a vy commodore and I’ve recently put another power steering rack in not sure what it’s out of as it’s a speedway car, what I’m wanting to know is what hole is the high pressure and what hole is the low pressure and are all racks from vt-vz the same some holes line up across to the left and some to the right big hole up top and big hole down bottom sorry if this is confusing but I’m more than happy to have a conversation with someone about it
