Here are the fuse/engine area formers. Tack the 2 ends on 90 degrees with main former and slide them up under and behind the lips after putting your glue behind these lips. You can put a small tack of CA from the smaller 2 formers to the outer lips or flange to hold it in place. Put the engine nacelle in place and make sure both long stretch of lips on the left and right side fit flush with it. You can pull the engine nacelle off while holding these longer lips in place, mark them on the former and put some spring clamps along the stretch of these lips to hold the lips against the former. You will probably want to put this section in after the rear wing section.
