I recommend that you link up with boys from the 2nd Arkansas. They have a Facebook Page and they are currently pretty active in re-enacting. While the two units weren't formed from exactly the same area, the did form about the same time and both units spend much of their existance in the Confederate Army of Tennessee, so they were drawing uniforms from the same supply depots.
