Sorry for the delayed response. We lost some friends and family and took a break from the internet mostly. Thank you for the reply and pics. How did it go on the inside? Prior to last November when I planned on doing this, it looked like a 'BEAR' to get to the heater core. Was it not actually that bad?
My other go-to was going to be one of those generic Heater/AC kits you can get for under the dash at a cost of around $400.
