Factory heater delete

Back around the early 2000’s, I saw a 68 Dart 4 door heater delete car still in use in California. A little while later it was wrecked and I got a few pieces off of it. I never paid attention to the block off plate on the firewall or if it even had plastic defrost louvers on the top of the dash. There’s probably a few unique items for a heater delete car. Did it have a fresh air box on the passenger side? Were there block off plugs on the intake manifold and water pump? Or was there a loop?
