Well I worked on the Jeep pretty much all afternoon/tonight. USPS brought my Vibraflex and the evap cooler. I did the deadener first so it would have more time to stick and be warm. We have a radiant heater in the garage so it's like the sun beating on the roof. I barely had to use a heat gun, I left a spot in the center where I'm sure I'll have to weld a windshield brace. I need to get some spray foam on the roof B-Pillar brace it's not even attached.
Phase two was the more in depth project. Pulled the dash to replace the heater core, heater hoses, evap core, blend doors, and blend door actuator. I also moved the passenger side actuator to the recirculation door as the new blend door I put in made it useless. So now my heat now works great which is much needed.
Heater box out:
Old heater core next to new the evap core was full of dust and crap too:
