I've got one of those. I mounted a cigarette lighter socket under the dash with a toggle switch to turn it on, and I use it just to defog the windows in the winter. If you wan to use it for heat, better forget it. It wont take the chill off, even on a long trip! At least they're cheap, so my $10 sale price wasn't a big deal. I've got a couple NOS heater cores sitting in boxes here, and I'm going to mount a pancake fan behind one, and then fab a sheetmetal box to cover and mount it all. Much better and cheaper than a aftermarket hotrod heater.
I also have one of these in my Aero , they are very compact and weigh only about 5#. Works great although they are 6 volt so you may risk burning up the motor unless you use a dropping resistor. They have 2 air exit ports making them really easy to install.
has defrost as well... you will need to find the parts that go up under the dash by the window for defrost, if your car did not have a heater installed originally they will not be there.
Guys, call Roland at Rods and Rides in Calhoun Ga. 706-625-4518 (Shop) or call him on his cell at 770-324-4098 He has a really neat self-contained under the dash unit for $170. It's compact, ( 7.5" x 7.5" x 7" tall) and easy to install in just about anything.
That Summit trans cooler with a fan is similar in concept to the auxilliary under the front seat heater I had on a 48 Chevy. Seem to remember a large round hole in the floor for it to pull air though.

I used the Flexalite 640 Mojave Heater with the 650 Plenum box in my Henry J Gasser project. Mounted it vertically on the passenger side, so I could tuck it behind the dashboard. We welded some 3/4" square tubes to the inside of the firewall and used nutserts to hang the heater off of, so no fasteners show on the firewall. I may have to reroute the inlet fittings and add a bleeder to get all the air out, but I really wanted defrosters even more than heat. John

I am looking at doing one of the 12V heaters (no water lines) in my little 27 Model T coupe. Does anyone have any experience with the heaters that DO NOT run water lines? Are they worth installing? I don't need to be warm, but a defroster would be nice and a little warm air on my feet would be a bonus.
