I was at a show today, without my car, where the Model A class winner was a 31 deluxe roadster with a rear mounted spare. Didn't all 30-31 deluxe roadsters come from the factory with at least one sidemount?
'30 Models came with a sidemount and a rear trunk rack. '31 Models came with a rear spare. It's hard to find a 31 that hasn't been converted to dual sidemounts and rear trunk rack, but there's a few left. I have one.
