Bend the pop-up fins back a bit so they stand out more prominently. Bend it slightly at its base so it stands straight out from the tringular truss, in a plane perpendicular with the gold. Make a crease along an imaginary line connecting these notches. Adjust so the shield is bent, gold towards gold, about 30 degrees. Fit the V-shaped notch up over the RTG where it meets the boom, and secure with glue.
Gold faces outboard.
