The C172 had a closer template to match the color. I didn't do this very often, but in the this case, it was utilized to take advantage of the plans.
You're call, you can easily use the 172 in these plans. If you're a purist, then you may want to disregard these plans.
I'd reconsider the 182 but the available templates are not that close. You're call in the end, but thanks for pointing it out.
