Thanks man.. Yeah it was a template I sent it. not measurements. I love the system.. the color is perfect, the density the ventilation. I have no complaints other than the front wants to ripple a little bit. I am sure I can figure out a way to glue it so it doesn't ripple. but it does have a tendency to want to do it. I have to check and see if their are pleats.

2nd picture is another system with temple flaps.
