Transfer case skid broken bolt/nutsert

Determined the squeeling coming from my front end was the driveshaft. Successfully unbolted the drive shaft from the axle but to remove it from the transfer case I’d need to drop the skid plate, drivers side all the bolts seemed to come loose easily, not the case on the passenger side, the first bolt loosened but broke the nutsert free in the frame. Not sure what to do from here, I’ve tightened the transfer case skid back up aside from that one bolt and I’ve tied the DS off on the frame. I’m kind of learning as I go along but I’m just not sure what to do next?
