I've decided to start by replacing the front shaft, guibo and bolts. Hopefully this isolates my clunking issue.
On second look, the rear driveshaft slop that I was seeing is actually the rear axels/CV. The shaft itself still has a bright white sticker on it which makes me believe it simply cannot be original. I'm not sure how much slop is supposed to be present in the constant velocity joint.
Considering the rear shaft is a bear of a job compared to the front, plan is to start with the front and bolt it all back together. If there is still slop then we will go from there. Hope to order parts tomorrow and put it back together early next week.

So what's the condition of the internal splines of the output shaft in the TC that the driveshaft goes into? Hard to believe they are good if the splines of the driveshaft are completely stripped. If the inside is stripped, you can either get a driveshaft that has a bit longer splines, (thereby engaging the undamaged part of the internal splines in the output shaft), or replace the output shaft in the TC, or BOTH. But a stock shaft if the output shaft of the TC is already damaged will not last long.
Here's where you can get those parts:

If you DO decide to replace the output shaft, I would certainly do all the bearings and seals in the transfer case, as it's got to come apart anyway. You can get a good look at the chain at that time, ($90 to replace). This site also has a video on dissasembly, it's really not that hard.
