If you order that kit it will contain instructions for locating the static ports. I believe the later kits actually have a pre-punched pilot hole to locate the static ports (I'm sure someone here can confirm/deny that). My kit did not have that hole if I remember correctly.
Basic pop rivet system works great. The location has been moved once in the past 18 years per the newer plans, easy... cost effective method for sure. I've had zero problems with mine.
