Alright give it another try, I updated my files since then and re-archived the set, it now includes all the decals that go on the NCWTS and NXS vehicles. Still need to do the groupings but you have all the decals needed to build any of the 3 series. Included updated Coors pole decals by Jim C.
Resize the total sheet to 2900 x 2330 pixels. That will make them the right size for the Gen6 bodies. The decals are all made to fit a Cup12 body, as that is when I started doing full layouts like this, so my decals are all to that scale, the gen6 body is smaller in proportions mod wise and so you need to reduce them down. Reduction is much easier as it doesnt produce quality loss normally, but if I built them to small and you have to blow them up you loose quality.
