New carpet install ???

[72gmcshorty]

I have a new carpet I just took out of the box. It is very creased and was wondering how to get the crease out. I can't just lay it oustisde because it's too cold and not sunny enough. What can I do. Should I glue it down or just lay it down, mount the seat and the chrome trims on the floor and call it done? If I glue it down, how much prep work is need on the cab itself? I guess I cut the holes for the highbeam switch first. What about those two little round ball things that the 69 style gas pedal sits on (mount on the floor) will they stick out high enough through the carpet? Will the carpet interfere with the gas pedal? Sorry lots of questions now who can answer them all?
