Going to place these here for the geometry purpose.

From the edge of the upper column cover, the mating surface of the steering wheel sits at just about 120mm.

Part of the base of the steering hub/boss is concealed inside the upper/lower column cover.

Depending on the design of the steering wheel, the position that you grab the wheel with your hand doesn't necessarily sits at the same plane as the centre section
so please use this 120mm distance as a reference only.

Best creating model using cardboard or something and attach your steering wheel to get the feeling before installation.

It is important to check the distance to the turn signal lever and wiper switch with your hand still on the wheel.
