Don't need a radiator then!
I wondered why my defroster wasn't blowing much air and finally figured out that the hoses (near your feet) were all cracked to heck and falling off. I replaced with generic aluminum stretchy bendy stuff from Autozone and now it works great. Also doesn't hurt to lube up the deflector... 30 years is a long time and rust builds up in there over that period. Mine works great now.
How many positions are there supposed to be on the deflector in a '76 FJ 40? Mine seems to have 2 but neither position puts out any air on the windshield. The only way to get defrosting is to open the window.

I know the purests wont care for this but I went with the Summit Racing heater with the grill front. I added a couple of hoses to the front and ran them to the defrost/defog vent. I still wasn't happy with the defrost/defog and bought 2 40mm x 40mm x 10mm 12V computer cooling fans and put one behind each duct tube to force air to the ducts. The fans are on a seperate switch from the heater so I can control the defroster (and yes it will defrost now). The heater was sorta expensive a $160 but I like winter wheel'n AND being warm 
and now with the addition of the two fans I'm very happy with the setup. I would like to change out the hoses but it was all I had at the time.

They're just the standard computer case fans we are all familiar with, I'm sure. Standard sizes are from 40mm to 120mm, with some fans designed for quieter operation. The 40mm is generally the loudest, and the shortest lived. There are varieties with fan speed control, too. Non-variable speed have two wires, variables have, IIRC, three.
Your local computer shop should be able to fix you up - spend the extra, and get the ball-bearing variety.
For extra bling,
you can get them with LEDs now, too:http://www.newegg.com/app/ViewProductDesc.asp?description=11-999-455&depa=1
If you need an online place, I recommend www.newegg.com - great service, good selection, often the best prices among reputable vendors.

Flex-a-lite makes the Mojave heater which looks like it will fit similarly to the summit one. Might be cheaper, I think I saw them for $180 canadian. Too Tall found it after he spent big bucks for a hot rod type one.

260 CFM, 28000 BTU on the heater. They also make a smaller unit, which would probably be just fine with a rear heater set up too. I saw an identical heater in JC Whitney made by Acu-Heat and they are selling them for about $20 more then Summit.
6.48 CFM on the 40 x 40 x 10 fans, bought 2 on eBay for $7.95. Don't know if the price is good or not. For working defroster ducts I was thrilled. Not pimp'n this guy or anything but here's where I got my fans. I also bought a pair of 60mm's from him in case I didn't like the 40mm's. I may put the 60's in just to see how much difference they make.

Kirk, thanks for the link. I am concearned about how long the fans would last. For the price of these and how cold it's been, I didn't care at the time. How that I know it'll work I'll get some better quality fans when these go south. As far as the noise, these 40mm's are advertised at 24.5 dBA, and with the heater on I can't hear them.
I looked at the flex-a-lite heaters too. I opted for the higher CFM and BTU, but again, mine before I added the defrost ducts would blast you out of the truck. With the ducts installed in blocks enough of the air flow be about right.
My 78 45 blows cold air through the center vent all the time whether I have heat or defrost on. It doesn't make any difference whether the fresh air is open or not. I need the fresh air open to keep the windows from fogging up but then I don't seem to get as much heat as when I recirculate it. Is that normal or do you think that would be a seal or something leaking? Also when the fresh air is on the blower is a lot quieter. Anyone else notice that? I can almost hear all the rattles and squeaks then. pete
