Nv4500

I'm starting to put together my frame up resto and I ran onto an issue. I just installed my NV4500 in my 83 CJ-7. Once the transfrer case was on I realized that I have an extreame driveline (driveshaft) angle to compensate for. The transmission is almost horazoltal and the rear pinion is sticking up at about a 35 degree angle.
Now I did expet the driveline increase, especially with the 4 inch Skyjacker suspension lift, and the extended lenght of the NV4500. The lift came with a pinion shim adjustment that I thought would slove the problem. Just in case I also installed a 1" drop bracket for the tranny cross memeber. It's the fact that the tranny dosen't point down a little that is concerning me. Has anyone run into this situation doing a resto. I know one solution is a constant velocity (CV) shaft, and I plan on doing this, but even with the CV it looks as though I will need to do something else as well. I was wondering if the additional weight of the body and rest of the jeep will bring down the angle? My other option is to lower down the transmission crossmember more. Anyone use more than a 1" drop on their crossmember to get proper angles? Any thoughts or sugestions will help.
Thanks
Ryan

You might want to call Tom Woods at tomwoods

Not only could he help you figure out your true pinion angle, but could also set you up with a CV shaft and or steeper shims.
