Alright, here's an update. I've had the truck completely stripped down, had the trans apart to replace the output seal, replaced the t-case rear output seal, new t-case rear output flange (I think this finally solved my leaking issue), nearly 100% fresh frontend (spool/axles/joints/hubs/rotors/locknuts/lockouts), and I freshened up my rearend as well (re-ran brake lines, new shafts/rotors/seals). Front driveshaft is balanced and a replacement is being made (should be done later today). Tom Woods is direct shipping my spare rear shaft to the start location.
My drivetrain should be damn near good-as-new.
The cage is done and the interior is back in. Yes the B-pillar is spliced. It's sleeved, plug welded, and fully welded through the 3rd brake light access. Glass guy comes later today to re-install the windshield.
I still have to plumb the line lock and pack up all my stuff. I feel like I'm sitting pretty good right now though, especially compared to how I felt last week at this time. I've got a lot done.
Here's some pics too.
Shitty pics, I know. Most were taken while burning the midnight oil. Lighting isn't the best in the shop.
