b24_witchcraft, when I understand you correctly, you want a 31FG repaint for the FSX acceleration Mustang. I have been looking at the usual places, but couldn't find a paintkit for this model. I think it is too much work for most of the repainters to create a full paintkit from scratch, just to make this one repaint. (at least it is for me)
When you want a B or C model P51 and are not willing spend any money on it, you could try the P51B/Cs from A.F. Scrub. You can find these at Flightsim.com. Just search for the files mustangp51b-c.zip, mustangp51b-c1.zip and mustangiii_fix.zip.
As I don't think these models support "shine" you will not be able to create (or find) any reflective textures for them.
When you really want to have a model from the aircraft you show in your picture, there is no other option than to spend a some money on the Warbirdsim P51B package and get the repaint done by JanKees. I can assure you that you won't regret the money spend on the model.
