I here you man. I started on the GPM F-15 a few years ago. They "tortured' you with installing every rib in the wells, but when it came time to skin the frame they didn't mention installing the things. Being a Noob, I thought they'd figured a way to put'em in later, you can imagine! Anyways, this is shapeing up to a spectacular kit and build, great progress and well wishes, and very well done!
