Come on!!!!! Those blisters were put there to accomadate the extra length of the resistor plugs and that is for radio suppression. Since far and away the most Coupes built were done so at the factory in 1946, 99.5% is way out of line. You may be right about the FAA though. I had to put blisters on mine two years ago and it required a 337. As you say, no big deal as many newer coupes had them from the factory and I mean newer, not 1947. Ultimately, you'll be better off working with the FAA than against them as they usually win. Jim Powell N99068 S/N1691
