More interference between the the right C-622 Canopy Release Link and the F-643-1 FWD Fuselage Channel. Holy moly, will the interferences ever end? DWG 24A actually shows a hole similar to the one I'm about to cut in my F-643-1 FWD Fuselage Channel. The drawings don't give any dimensions of this oval hole. You just have to make a hole that fits your particular installation and interference.
