Then do things in the correct order. Don't cut until you HAVE the headers. Every car and every set of headers are both a little different. If you try to use a template now, without the headers, you'll surely need to trim something else later. I can almost guarantee it.
Understandable. Solid advise. The car I’m working on is the biggest mess I’ve worked on and I teach auto body to high schoolers. I’m getting there but it’s a slow process.
