So, I swapped in 2* shims friday. While I haven't achieved a 90* between the driveshaft and the pinion flange, I've got a flatter driveline and now my vibration is gone... so I've at least made some progress there. If I did this again though, or for those doing this with a similar setup, I would go with a 4* shim as the factory one is an 8*. Side note: The factory shims are located to the leaf pack with 7/16" "pin-head" bolts. If you get the shims from JBG they will have to be drilled out to work and bolt to the leaf pack, but they are designed so you can do that. A hand drill is fine for this.
Here's some pics...

I've also got a couple of ideas for the future.
I've noticed that the transmission crossmember is the next lowest portion of the frame. I think I could scavenge a little more ground clearance by making a new crossmember and using a C6 transmission mount from something else, like a 70's mustang or Galaxie. Have to do a little R&D, but I think I could make it happen.
The bronco's cheap exhaust job is also falling apart. Its something one of the PO's put on before me. The Y-pipe for the duals is full of huge holes so its not worth keeping. It also fills the back with fumes when the back glass is down and I'd like to ride with the top off at some point this summer and when I go coyote hunting. I think a side exit coming out before the pass-side front leaf mount would work well. I just need to get a hold of some pipe and get to work.
I did put my red LEDs in for the front and the back dome lights. The front light is also a swapped-in ford mustang dome light. I wanted just enough light in red to see in the cab to keep my night vision while going on hunts or just being in the dark, and this accomplishes that. The bulbs should be around 175lumen in the front but only 75 in the back. (Links to LEDS: Front
). I would like an auxiliary light in the back though... maybe dimmable LEDs or something.
