STEP 4 - Attach spinal column to the Neck as shown in Fig. 7
STEP 5 - Attach the Rib Cage
The rib cage comes in two halves. Place the spinal column with the organs
into the rib cage. To line up the rib cage for proper assembly, along the top
of the rib cage there are 3 notches. Each one of these notches is for one of
the posts that stick up from the spinal column. Set the spinal column
assembly into the rib cage aligning the posts into the notches. Then place
the second half of the rib cage over the organs and fit the two halves
together. See Fig. 8.
