I did this a few years back, rough country 6.5, threw 2 inch rear blocks and 2.25 front spacers under it, did a half ass job, didn't adjust my pinion angle or get an sye, bad idea... if your going to do this, for your own sake I hope you do it right.
The beater jeep, I am sure I can find a picture to show u of the finished product, could dd it fine but offroad the driveshaft liked to come out
lots of driveline vibration.
