GM,
I don't know about an existing template, but when we reinstalled and recovered after repairing the right fuel tank we repainted ourselves. I took a tape and measured the left wing and laid out the scheme on the right. Except for the stars themselves, everything is a straight line with a beginning and an end.
If you are having a shop paint it, any decent shop should be able to lay out the scheme from a photo.
Here is what the top of ours looks like.
