Trailer Hitch for 1975 Plymouth Duster

I'm going to duplicate that one, I like the way it's built. U-Haul has agreed to use my car as a template to build a hitch for free. They do it so they can produce a hitch to sell to the public. Big drawback, 12-18 month wait time. We're planning on doing a drag n drive in October and I need a hitch.
