I get this clunk in the front end when I come to a stop. I just started (I think). Any thoughts?

 

Is it when ever you stop or just when stopping fast? It could be a lose shock bolt.

 

Crawl under the rig with a pry bar. Reach up over the axle and work the locator bar end that is up on the driver's side frame member. Judging from the age of your truck, my guess is that it will be loose.

If it is, go to one of the aftermarket sources and get a good replacement link kit. The OEM replacement is not worth dragging home, and costs twice the price of much better aftermarket kits.
