How to remove Heater Box in 68' Dart WITH factory Air

This was my first attempt at removing a heatercore from an old Mopar with A/C,so was scared about breaking any hoses to the A/C(hard to get around here)I also was replacing the top and lower dashpads,defrost vents.I removed the front seats for easier access too.I was schocked to get a replacement core so fast.Parts stores here usually don,t carry parts for 1968.Anyway I got it all backtogether,but can barely move today from working up under the dash.Next time I will know to remove the complete dash as a whole unit.Removing the speedo bezel without damaging anything was a real PITA.
