"Loud clicks", that's a symptom of a discharged battery or a loose connection or a faulty starter relay. Did you inspect all 4 cable connections ?
Before popping for a new starter I would use some jumper wires to bypass the electrical system to make sure the starter isn't working. Unplug the green wire from the starter. Put a jumper cable from the battery positive to the stud on top of the starter then a smaller jumper wire from the battery positive to the spade terminal where the green wire plugs in. The starter should spin and engage the clutch ring gear.
Actually you can try just jumping the green wire terminal by itself first.
If the starter works I would start checking all the connections and relay.
Note: The tests are done with the ignition off.
