AFTER the wing is rejoined as well as you can get it (use 30 min epoxy and push together if you can) you can remove the servo from its "tray" and test fit into the wing. If it fits well (trim if needed) carefully epoxy the tray back in place. 30 min recommended to give you some working time before setting. When FULLY set reinstall the servo. The dowel looks loose so it will be easy to replace.

Plane suffered a HARD landing mostly on the nose gear. Remove nose gear wire and place in a vice to straighten. If firewall crack isn't too bad (can't see it) just drizzle some thin CA glue into the crack while holding parts straight. DOn't glue fingers to the plane. Make sure firewall has NOT come loose from fuselage. When firewall is fixed reinstall nose gear.
