Got the drive shaft back from Cleveland Clutch the next day. Very quick turn around. I am going to paint it, however.
Took an angle grinder to the Barnes 4WD rear track bar bracket. The Rock Krawler track bar is so fat that it was hitting the bracket.
I also had to rotate the track bar back a little. It was hitting the diff cover a bit. With it rotated, the bend will pass by the cover. The ARB cover is just so thick.
A couple more things checked off the punch list!
