I used a fly cutter in a hand held drill to cut two fan holes in the glare screen. By taking my time and doing it slowly, it turned out great. I then lined up the vent fans and match drilled the four fan securing holes. The doublers were match drilled next. Once they were done, they were alodined and dried. I finish assembled the fuel injector/air box. It is now ready to mount to the bottom of the engine.
