Heater box question... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am trying to get some kind of idea on what to do with my heater.
I really like the looks of a shaved firewall, but sometimes you need to have heat(don't want to put my truck up for 5 months because of no heat).

I see some people have shaved firewalls, with two heater lines run into the firewall and no heater box in the engine compartment. How is this done? This is the direction that I would perfer to go. Keeps the engine compartment clean, and have heat.

Also, if I decide to use my stock style heater box, what is the best way to clean and paint it to look better? Is there a way to get it smooth, and painted with a gloss finish to match the firewall?

Thanks,
Nick

The smooth ones you see will be aftermarket systems like Vintage Air or Old Air.

I've always had real good luck with sanding, thick filler primer, more sanding, and painting the stock boxes. They turn out super slick that way.

The guys that are doing that, (myself included) are installing either an "Old Air" or "Vintage Air" system into their truck. They have a small Box that is mounted on the inside of the firewall. WES www.ClassicHeartbeat.com

I don't want A/C. Do those systems come with A/C or are they just heat?

Thanks,

If you want heat and defrost get one of these. They work good in a small spacxe like a truck cab. You will need the plenum kit to run your hoses.
