Well I extended all my breathers this morning. It took me about hour and half to go to the store, pick everything out and drive back and extend the breathers.
$20 for 10 foot of 5/6" hoes, 4 brass connectors and 8 clamps.
The front diff was the easiest, i extended it to the brake booster and tied it to one of the other hoes.
Rear diff was not that hard either, I found it right next to the gas tank and extended it few feet and clipped it to the pinch weld next to the gas cap.
The tranny breather was not hard to find, I followed the groung wire from the firewall to the block and right there was the breather. I extended it to the brake booster also.
Now the transfer case breather was pain in the butt.
I found it along the tranny dipstick and it was very dirty, I unhooked it from the block and tried pulling the breather cap off with no luck.
Finally after fighting with it for good 20 minutes, I took scissors and cut the hoes little below the breather cap. Since I was in the bind doing all this the cut turned out on the angle. I got my new hoes with the barb connector and tried inserting it into the transfer case hoes but it was so slick I couldn't hold it. I couldnt really get to it to clean it up either. So I sprayed some silicone lube on the barb connector and after another 20 minutes was able to put the connector in the transfer case breather. Since I cut the transfer case breather on the angle, one side of it was all the way to the top of the connector while the other side was way down. I didnt want to take it off and try cutting it again to make it even, instead I got a clamp and put it aroung the transfer case hoes and barb connector where the lower side of the hoes was. I also found some gutter sealer that is water tight and waterproof and I applied it all the way around the connector where one side of the transfer case hoes was lower than the other on the barb connector. I hope that seals it good enough.
When I went to the store I bought some clamps that I was going to put on each hoes on each side of the barb connector, but the connector went in so tight everywhere, I didn't think the clamps where needed plus i can always put them back on if I need to.
And without the silicon spray I could of never put those barb connector into the hoes.
I thought I would let you guys know how it went, and any comments are welcome if you think I did somehting wrong if you think there is a better way of doing something.
Also the transfer case breather is indeed located along the tranny dipstick, right?
Sounds like you were really pimping your KJ w/ all those "Hoes" around it. 
) Right now I figure the top of the rear diff tube is at least 35", and the front diff and trans tubes are 40" above pavement. If I can get the t-case tube that high I'll be happy!
