Pinion needs to be lower...

I'm putting on my new upper and lower adjustable control arms I have a transfer case drop installed. my pinion is at 12 degrees and my drive shaft is @ 9. should I make my lowers longer or may uppers shorter? I will be getting a SYE/ CV, hopefully in the next few months

What we need to know is the angle of your output shaft. The pinion angle should be within 1°-2° of the output shaft, and the drive shaft no more than 15° difference between the two.

You are getting to the fun point when every adjustment effects something else.

While you have the T-case drop you want this.

When you put the SYE and CV shaft in, you will need to adjust to this.

The trick is to keep as much wheel base as you can, but you also need to look at how the tires stuff into the wheel wells, and watch the track bar and gas tank clearance. has a nice write-up for adjusting the pinion angle that might help.
