How do I hinge doors on a drag car?

[am73grand]

I've seen that most of you use a wire bent 90 degrees and then you have tubes on the doors that slide over the wire.

My question is: How do you know where to put the wires and how far to make them stick out so the doors operate properly?

Thanks!!!
