Where is your driver's seat located?, In the car, I know- but is it centered behind the wheel? Options

[rjames]

I replaced the driver's side floor pan, and before welding in the new seat bracket mounts I noticed that it seems impossible to actually get the seat centered behind the steering wheel.
I say impossible because the 'claw' that is attached to the cross brace on the floor pan (the one that's used for the seat tilt adjustment) forces the placement of the seat to some extent- which in my car seems to be off an inch or so to the left of center of the steering wheel. Is this normal?

I've been doing searches for pictures of cars with the roof off viewed from the top down, but haven't been having much luck.
