It would actually be quite hard in comparison.
It's actually easier to just tape the paper on, trace the back and top body lines, punch the holes by sticking the emblems back in and tracing around the emblems for added insurance and send it to someone as opposed to going out and building a layout and measuring all 16 holes including the side markers from two different angles. Tracing it on only takes like 30 seconds.
It's also much easier for the recipient, I was a recipient at one time. Took like 15 seconds to tape it on and mark the holes vs measuring them all out. You just place that template on your car, line it up with your body lines, tape it down and mark the holes and drill. It leaves only two lines that you can make any mistake vs all the measurements you have to transfer and measure out. I do understand what your saying now but I just like the simplicity of the quick and easy template and I have no issues going out and making them and sending them to whom ever needs them. Honestly I wouldn't trust my own measurements on that many holes, I'd be sure and get one off a fraction and someone would drill it and have it not work and I'd be to blame, at least I'd feel that way.
I believe there is already a measurement in one of Pauls books if that's whats someone wants, I could be wrong but I think there was, been years since I've looked at either of his books. If not and someone wants to do all the measurements and mark them all out that way feel free or if you want a template let me know and I'll get one headed your way.
Jon, send me your addy and I'll get these two headed your way for the scanning.
