Picture of 4 speed hump needed

Since the only early A-body reproduction four speed humps out there are fiberglass I am going to make my own. To that end I need a picture of the hump from above with a tape measure or some kind of measuring device next to it so I can figure how the dimensions and where it goes.

Of course if anyone is near Elkton, MD and wouldn't mind me coming by to take some pictures and measurements, that would be even better.

TIA,
Wayne
