I have a 54 3600, and I'm Changing over to a 12v system with a 383. It currently has the Air Flow Heater that attaches to the passenger side wall. I need to upgrade to a 12v system but I'm wondering if there are any heating systems that could go in that wouldn't require the hoses to go through the firewall? I really like the look of a clean firewall and I have been working to relocate as much as I can going through in the stock holes, but I'm getting stumped on a heater system.
Open to options, advice, and ideas. Thanks
