With the FPE I will need to do the same on the left side. It would have been so easy to mold the cowl 1/2" wider and not look out of place. Its strange because Marcello's has a 3W 106 in it and the left plug is cut out. If you take a good look at the cowl it starts to taper in from F2 (back of the cowl) other planes like a Carden taper out until you are about 3" from the front. Maybe I'll e-mail Marcello about this. It most likely will not do us any good but you never know.
