So I just picked up my first van, a 1977 GMC Gypsy, and there’s so much heat pumping out past the doghouse, all the insulation on the firewall is long since gone, what’s my best option to try and squeeze in there and re-insulate my firewall and what are my options about the doghouse? I live in Phoenix and with digits hitting triple digits now and no AC I need to find a solution[img]https://imgur.com/gallery/Br6JWta[/img]
