I should have written the number larger in space for the decal, not your falt, the number is just fine. Here is a pic, I should have painted out to the orange box not the green.
I changed the numbers in the dds WP5357_gp38_2_diff to match a real Western Pacific GP40 witch I used for reference. I just need an alfa for the number on the side of the cab wich I posted. If anyone could create one that would help. thanks! I will edit the XML so that the engine is the right scale.
I think I still have a png of the new number for the side. I remember trying to add an alfa to that. If I find it I will try to add an alfa channel again and if I do I will remember how I did.
