Hedman 75110 fenderwell header cut out templates

I have a set of hedman H75141-6 but they are 68+. If there is any relevant info I can give you, I'm happy to take measurements. I don't know if Hedman would have any internal reference to compare the two. May be of absolutely no use to you, but I wanted to chime in because I also "started small" and my holes ended up bigger than I wanted them. So my advice is to start VERY small...and cut / grind 100 times if needed. my car is no show piece, but it always disappointed me I didn't do a better job on this.
