As I stated earlier, the Skyhawk's main gear was attached to the lower wing , but not inside. The struts had their own fairing and the gear swung forward during the retraction. Only the main wheel was stored in the wing bay.
The fairing ( canoe like shape ) wing frame is pre drilled to position the gear struts
here are the parts of the fairing
glue in place. Note that the red outline is hand marked. On the real aircraft it is there as a safety marker so you don't bang your head and face on those edges.
