My Coronet has AC and I was able to pull them with the heater box in and the gauge cluster, harness, radio and glove box liner out. As long as you have the wiper motor arm unbolted from the motor or the clip and cam removed, it's just a matter of removing the two nuts from the cowl bolts that secure either pivot housing. There's a foam seal between the hole in the cowl and the pivot body that makes them stuck in there pretty good, but a couple thumps from a rubber mallet will get em out of there all in one piece without disassembling the whole deal. I restored and reassembled mine and got it all back in with a new seal kit, easy peezy. The wiring harness will likely be your biggest battle.
