Fuselage - Cabin
I checked-out a few websites on drilling the flap rod holes, and it looks like you just cut the holes until things fit. This turns out to be an oddly-shaped hole, as my experience would suggest, so carry on.
BTW: Not a lot of websites show this hole. Probably because it looks so ugly, but it is what it needs to be.
|After a few dozen iterations of "cutting", "attach rod", "run up and down", "remove rod", this is what I ended up with. View from the top side.|

|View from the side.|
|Full down (backside).|
|Full down (frontside). This is very close, but I don't want to remove any more metal near the rivet.|
|Full down (straight down). There is clearance, but did not get the shot.|
