I think its bad, like all of it.

its broken off, and barely sticking out the other end. i loosened the other one all the way so both of them are as low as they can go. that thing is thick! looks about perfect, but i read someone else has a gap just like it and it rides fine, but they swapped out for bilstein shocks. maybe its been my shocks this whole time?

If you want just the bolt, you might try FB Marketplace/Craigslist for a truck getting parted out. Or a junkyard. These are not parts that typically go quickly. You can also look at those trucks to see how stock might should look, to better understand what you have. Finally, if the bolts are the same on both sides, pull the good bolt and take it to the parts store to get two new ones. Even if the bolts are $5 each (which they should NOT be), $10 going into your suspension is nothing. Also, see if you can determine the maker of your lift kit. Contact them and get information from them.
