Our lemons mustang was gutted during the summer time.. So the heater/ac box is long gone. Its looks like we have a winter mix for next weekend for the CMP race. I have no way of making a metal heater box, so can I make it out of 1/4 inch plywood? One of our guys has an old box out of a 240z that has a good heater core and squirrel cage type blower. I thought about building a small box to house the heater core and a way to mount the blower to it so that I can pipe the air to the windshield and drivers area with dryer exhaust vent flex hose. Also would you take the moisture out of the heated air?? Little air dryer packs you get at shipping stores?? I know they make anti fog but rather have two ways to help keep it clear and WARM!!! ;)
thanks

make it out of wood, dont worry about the moisture. enough heat blowing at the windshield will clear it up. if you really want, use rain-x anti fog on the inside of the glass.
I'd just go with a 12v hair dryer.
Draw outside air to get rid of fog. If you recirculate interior air, you blow the moisture from your hot breath and sweaty pits on the cold windshield.

Not homemade, but a lot of the rally guys use these in their cars when the stock heater core has been removed.

Searching SpecialStage (rally forum) came up with a few other options than spending $200 on the Mojave heater.

Find a watercooled VW Vanagon at a junkyard, under the rear seats is a self contained heater. It is a heater core/blower in one small package. Just hook-up the coolant lines, a switch and fabricate a duct pointed towards your windscreen a your done.
I've also seen a number of these Harbor Freight heater/fans used as defrosters in race cars.

Whatever you come up with, you should post it to www.thereifixedit.com.

Those harbor freight heater fans are junk. I currently have one in my miata pointed at the rear window (non defrost hard top). If I leave it on for 30 min, I get a 3-4" circle that is fog free. It does not move nearly enough air to be useful.
