(12/17/07) We got pounded in the Northeast with a ton of snow over the weekend and I spent most of my time removing the snow. I was however able to get out on Saturday night after we did a bunch of running around to get ready for the snow.
There was a heater setup in the YJ body I bought when I got it, however, it was not going to be able to hook up to the CJ dash. So, there was the dilemma. The YJ heater was much stronger and pumped out more heat while the CJ heather had all the connection points that I needed. So, what if I could have them mate and produce a hybrid offspring... brilliant!
I took off the CJ's blower motor and cleaned out all the crap that was in there. I then moved onto removing the back cover and chucking the heater core. It was sealed shut on one side and there was a lot of junk in there to boot. So, I cleaned up the housing the best that I could and moved onto removing the YJ case.

NOTE: I had the thought of using the heater backing plate of the YJ and bolting on the CJ front face, but there in lied the problem. The CJ case had 3 of the 4 bolts necessary to bolt it to the firewall NOT broken off. The YJ case had all 4 broken off. As you can see in the picture of the bolt that I am holding, they are tacked into place with 3 spot welds.
So, I removed the broken bolt/stud and moved onto sticking a similar size bolt in its place. I held it in place with a nut and it seems to have worked out for me. I hollowed out the YJ heater box and moved all the guts over to the CJ side of the house. I took the lower vent as well, so now I will have it blow onto both sides instead of just straight down.
I bolted it in place to make sure it all lined up and everything is looking pretty good. It needs some paint and I need to do a few tweaks to the moving mechanisms as they were rusted pretty badly, but I am happy. I get the best of both worlds. I have a new heater core and a new YJ blower motor, which blow more air and should be hotter, plus I have bi-directional heat now instead of straight down. I can't wait to see how it works. Maybe next winter?
