Differential is mounted!! 

After a grueling install, I have the front did installed!!
Be ready to hate this thing after you’ve decided to keep it. Had I not wanted to keep 4x4, this would have never been put back in!!
I would build another gmt800 4x4 again, and just convert it to 2wd. Just because of the better gear ratios you can use on the steering great trucks over the rack and pinion trucks.
I need the 4x4 though.
