Welcome to the Club! Nice ride and nice deal. Oh, and the correct year also.
You have the WWD (Wing Window Delete) carried over from 67 models......LOL.
Water stains in the trunk, no-no. Find out where the water is coming from and fix it.
Also, put the battery in an NHRA approved battery box and vent it to the outside. The trunk interior sheet metal will love you for it. If you decide to keep the battery in the trunk, you may be required to hook up a kill switch for the battery cable. May not be a bad idea anyway.
Also, if battery in trunk, measure the charging voltage at the battery posts. You might not have enough voltage to keep it charged 100% because of cable length run. measur ebattery charging voltage after driving 10-15 miles.
Alternator is ? (internal regulated or external regulated?)
Regardless, still a nice ride.
Congratulations on your purchase. I think you got a good deal on the car. Very Nice! I would address the following items:
Definitely install the battery up front.
The Camaro was not an original Rally Sport. You can tell by the tail lights. On a Rally Sport car, the Reverse Lights were mounted separately below the bumper. The Taillight Bezels had 2 red lenses and both were for brake lights. The new harness can be purchased from http://www.americanautowire.com/
Very Nice Car, Welcome aboard.
