If you do not know the difference between a Standard roadster and a DeLuxe roadster the parts you seek and the top are the principal determining factors. Go to some car shows and look at roadsters. Find out if a Model A Club is near you and meet some "A" folks. Take your time and decide if you wish your roadster to be a Standard, or a DeLuxe. You cannot mix the stanchions, windshield or top as they do not interchange. Take a bit of time to decide which way to go. Most folks restore a roadster as a DeLuxe as it is a bit fancier in appearance. This has made Standard roadsters a scarcity and un usual at shows these days.
