Chevy is better than most and heck of a lot easier to find parts for.
How about some pictures of this axle install? What R&P ratio are you running?
Hope you have an external cooler for that tranny.

Pretty much stuck with OEM size unless the OP changes out the yokes on the 2 pinions and the 2 yokes on the t'case.

Yeah. But he's got a GM 14 bolt rear end. That's already a BEAST. And the 44 shouldn't be a slouch either (although a 60 would've been a good match for the 14 blt)...
I hope he's running at least 37" tires....

With all the cool mods is it really a jeep or would it be more of a Cheep .... Joke ya get it a Cheep .... Chevy + jeep = Cheep 
..... Tried but I can't come up with another combination of GM, Chevy and jeep.

Mutt sounds a little negative, but some of the best dogs in the world are classified as "Mutts".

Thanks for all the comments. Sorry I'm a bit slow noticing I have responses. If there's a way to get notified when someone responds I haven't figured it out yet....
Anyone actually use Chevy drivelines? Aside from lengthening/shortening and a combo u-joint; any other concerns?
Thought about going bigger on the tires but this will do what I want (for now). I'm running SS Boggers TSL 35 x 14.5.
Apparently I'm not smart enough to upload a picture. I click the picture button and nothing happens.

When you click reply scroll down and find where it says "manage attachments"
This will open a small window then click on "choose file" from there you can find the pictures on on your computer. Double click the picture/pictures you want to upload and then click "upload at the bottom"

Pretty much exactly what I'm looking at doing. Keep us updated from time to time I'm interested in seeing how it turns out!

Did you move your steering forward and what leaf springs did you go with?

The springs are rough country. They are essentially stock with a little lift. I used Poison Spyder's outboarding and shackle reversal kit on the front which will take 2 or 2.5 inch springs and nearly any length spring. I did not move the steering gear forward. It has a 4" drop pitman arm reamed out from the bottom for GM ball joint and high steer to the passage side. It has a very low angle.
