Adding VU things (seats, lights) and 2d3d vehicle drawing

Hi there,

I have a car which has no VU seats. I have passengermod. I looked into the script and thought, how can I add a seat if I don’t know the position?
How can I get the position I need for the seat?

and, I want a screen in one of my cars, 3d drawed. is this possible, if yes how?

Thanks, Darrell
