AIM-9s are always on the outer rails. (Not trying to nitpick - the lightest ordnance goes outboard.)
Thanks for posting all of these photos MFH!! Excellent. Even on a coal fired modem, I'm more than happy to wait for them to download.
Actually F-16's usually carry the AMRAAMs on the outside wingtip rails now, you can see they are longer then AIM-9's, here's a pic of it.
