I had the exact same problem with my cowl. I had a two or three inch gap. I used some alum straps, approx 1 1/2 or 2 inches by 6 inches, and spanned the gap. I lapped the straps approx 2 inches on to the existing cowl and to the mounting points on the firewall, effectively bridging the gap with the cowl mounted in position. I then filled the gap with foam and glass. I drilled 1/8" holes in the alum straps on the cowl side and initially used clecos to mount before floxing and glassing in place. With 205 hours flight time there are no cracks in the glass where the cowl was extended. Your other option would be to first extend the cowl with glass and then mount. Larry Flesner
