BMX bikes have been using chain adjusters for years. 3/8" axle adjusters are now out of fashion in favor of the larger dia 14mm ones so 3/8" versions are abundant and cheap. There are all different styles: the super cheap and dinky steel ones that chuck mentioned, machined aluminum adjusters in all sorts of shapes, and real thick cromoly steel for the tough guyz. Some will work better than others, as the interface of a road dropout is obviously different than a BMX dropout. You'll have to modify the adjuster a bit, maybe bend and tug it to fit the dropout better.
