1968-72 A-body Heater Box core - NON AC

Want to find a good 1968-72 Heater Box - NON AC - for my 1968 Dart.
My elements are good but the fiberglass box is really messed up. Hoping to find a good core close to home to drive over & pick up.

Located in St. Petersburg, FL (West coast south of Tampa)
Can buy outright or have many A-body parts for trade.
