Iowahawk has a brief history of the hot rod:

Even back then Deuces were highly collectible. Car guys started hoarding them, heeding Mark Twain's famous advice to "buy land, they're not making it anymore." Strangely, though, they did start making Deuces anymore: high demand spawned an entire industry devoted to replica and restoration parts. Body repair panels and replica fiberglass Deuce bodies began appearing in the late 1960s, and are now available from dozens of suppliers, as are reproduction 1932 Ford frames. Recently several companies - such as Brookville Roadster and Dearborn Deuce - have introduced complete steel reproduction bodies. With a big enough budget, today you can make a pretty faithful steel recreation of a real 1932 Ford out of nothing but brand new parts. The paradoxical result is that 1932 Fords are more plentiful today than they were new. A scant 275,000 Fords rolled off the assembly line in 1932; today a greater number of "1932 Fords" are currently registered just in the state of California.
