Today my rear differential decided to "come unbolted " while driving through town to work. Now the diff is pushed down into my exhaust causing them to rub. anyone familiar with this that can tell me what would cause this to happen and if can tell me if I'm missing a spacer and would it be better to go with longer bolts ? Seems like Two bolts underneath disappeared and the two in the back popped out of place . Verify or correct me please
Rear differential issue, anyone know?

The diff brace looks too thick and the bolts too short to reach the mount.

That brace has been on the car since 2004 with those bolts
Hope the bolts that are missing , just fell out , not broken off or holes stripped.
I would get replacements and see if it goes back together and torques down to spec.
If there is damage , you will probably be having inserts installed in your existing housing , or replacing it .

The only thing that is missing in the second pic would be the vibration dampener, which really is not needed anyway. Those two holes are where it bolts on to.
And I agree those bolts in the first pic don't look long enough to adequately thread into the rear differential bushing, not sure how they held it for so long.

If those back bolts have been there since 2004 they weren't installed correctly. I vaguely remember my Billetflow brace coming with longer bolts. My guess would be whoever installed them didn't actually tighten them down. So the front two bolts were the only things holding the diff in. My guess would be the diff moved one too many times and broke them causing your current problem.
This seems to be what may have happened. Moved the diff back into place then replaced the two rear bolts with longer bolts and some loctite. Back to Smooth operation!
