I have a right hand mid fairing from an ST2 with a 2" split on the rear edge (the split is an easy repair and is positioned so that it would almost be completely hidden under the top fairing). It was originally in red with pre-2001 decals, but it's now in primer cos I have a 2001 bike and needed to replace the decals anyway (as you would to get ST4 decals). The panel is mechanically identical to the later bike.
I bought it from e-Bay to replace a panel I damaged in a lowside, but then realised that the damage to the original panel was all superficial and just ended up getting that filled and resprayed.
I was going to keep the repairable panel as a spare, but make me an offer if it's any good to you
