Thanks guys!
Sorry to ask such simplistic questions, but I want to do this right. I'd rather ask questions that seem foolish now, than not ask and have a terrible time at the tech inspection.
Not foolish at all. A lot of opinions get aired out on the forums, it gives a indication what areas are vague, likely to draw a protest, or might bring a future rule change. Words and opinions are easier to change than hardware, the vague and hotly debated items can be followed by up with a clear description sent off to get the official ruling on what your building. You add the official responce in with your build log and try not to trip up on the rules elsewhere.
My hope when my own build begins is that I or someone else has asked all the questions, sorted out the vague areas, had people critique pictures of the build, and have shown tech (when they have spare time) my vehicle part way through the build, so that hopefully it can pass through tech cleanly and start trial runs so both the vehicle and myself are legit to go for an official timed run. But then that's my opinion.
