They have two smaller units but I am going back with a blank dash so I have extra room with the gauges being put in a kickboxing mount and won't have a dash radio speakers or glovebox.

Wow! I neve thought of anything like these replacement heaters! I was planning on doing the blazer blower upgrade then sourcing out or rebuilding my whole heater since the PO removed all the wires & rods for the controls.

this looks easier and would allow me to mount a anywhere since i just have to run heater hose to it. sweet!

Does anyone know what approx CFM the blazer upgrade moves? So I can compare to these aftermarket units?

I didn't either. I spent quite a bit of time trying to get the old heater box with a blazer blower motor to work and just couldn't ever get the linkage to make it work right.

Got any pics of your set-up? Thanks!

Sadly, no. But I am planning on getting my CJ out of storage where it's been for the last 4 years in the next few weeks. I can grab some pics then if they're still needed.

******IF YOU ARE SUBSCRIBED TO THIS THREAD YOU DEFINITELY WANT TO READ BELOW*****

****This is copied from my build thread***** be sure to check out the links I have. There are several ways to mount this heater. Everything I've read online regarding this heaters has been positive.

Ok so I've been doing a bit of reading online about this Summit heater system. People are mounting them split blower in engine bay and ducting in the vent lines.

http://www.ffcars.com/forums/17-fact...tallation.html

This guy mounted his whole unit in the engine bay then only ran the ducts inside. Scroll down to post #4
http://www.ffcars.com/forums/17-fact...-question.html

I've decided that I am going to mount the heater box entirely in the engine bay and just cut three holes through the firewall for the vents.

Couple concerns with mounting the intake for the heater in the engine bay.

You will continually be using cold air, not the continually warming air that would be used if the intake was located in the interior, and the second is the quality of air you will be bringing to the interior.

85cj I am not worried about reheating the air. Most everyone has gone with the 16k btu heater but I went with the 40k unit. I do not have an enclosed top. In winter/rain I only use a bikini top, rear tonnue cover, and the half cab soft top rear section. I have lots of openings and it is nowhere near air tight or water tight.

Here is a pic from the engine bay
