Im new to jeepin and I just bought a 79 cj7 I think it has a 6 inch leaf spring lift, 35 swampers, 350 with a turbo 400, not sure on the transfer case I cant find the ID tag, and I also think it has dana 44 front and rear cant find any markings on either dana to prove it, my biggest problem is the rear drive shaft, I rotated the axle up but just by looking at it the angle is to steep and to short, has anybody had this problem and what can I do?
 
A picture of your rear driveline would prolly help. We need a little more info on exactly what drivetrain you have too. Can you describe what the transfer case looks like? Or post a pic of it? Is it an aluminum or cast iron transfer case? Does it have a slip yoke built into the rear, or does it have a fixed yoke?
 
the top diff pic is the front and bottom is rear

The last picture definately looks like its got an aluminum case in it. Probably a NP208. Doesnt look like you have a rear drive shaft in it at all. Do you have a rear driveshaft? You could do something like this

Or swap in a fixed yoke NP205, either way should shorten your drivetrain a couple inches and allow a slightly longer driveshaft You'll also need a new rear driveshaft with the slip yoke built into it. It would be a good time to get a CV style shaft so you can point the rear axle yoke up toward the transfer case.
 
Definately 44's. Not bad with only running 35"s, but I won't go as far as telling you that you can flog it. Swap that case for a 205 and have another driveshaft built and then see where you are on your pinion angle. 205's can be had all day long for dirt cheap and then you can spend the $$$ you saved on a good shaft.
 
No that will not work. That would make the axle drive in the wrong direction also.
Another option is to run a double cv / double cardan joint at the transfer case, that would allow you to rotate the axle up to point the pinion straight at the t-case. This would required a fixed yoke at the rear of the t-case and not a slip yoke. The driveshaft would then need a slip section in it.
