TODAY is a Great Day to visit our Store and order the parts you need for your truck!
I am not replacing the insulation that the heater box sets on top of. I am replacing the insulation above that. (Not sure if it was stock but it runs behind the defrost duct so it probably is stock). That being said I finally dropped the right inner fender so I could get to the lower studs on the heater box and remove them. Then I had to remove the dash board support bracket from the firewall and the dash board so I could drop the box out. Good thing I did as I found evidence of heater core leaking. Best to get it now. Thanks for the inputs!!ricky
The insulation is one piece, so if u are replacing with a factory Repo insulation it is behind the heater box also so the heater box needs to come out anyways.
