Yep, I have removed the turbine, helps on angle, but it's the stuff on the other side of the formers at the bottom of fuse and the fact the holes are right up against those formers. Pretty small holes so can enlarge them or move them.
I was thinking similar to Sean's method, and the way the wing tanks are done with tabs that hang, and the pylon is slotted to fit with a hole/screw on the side to secure.
