Truck rolled away ticking / not quite in park. caught it! The shifter was flopsy mopsy. Then when trying to start later, would not start and had to put in neutral to fire up. Found one shift linkage bolt sheared off (pictured) and one loose. Tightened the loose one, and the nub from the other is holding it from rotating and will hold until I can get in and extract the old bolt. I THINK they are T30 headed M6x1.0x30mm bolts, pictured here https://www.steeringcolumnservices.com/ford/05a-torx-bolt.php but will update this thread when I know for sure. Borrowed this image from fixya.com to illustrate where these bolts live.
