1968 Visor Replacement Help
 

Purchased TMI sun visors to go with my one piece headliner.

After removing the visor and it's attached mounting bracket from the ceiling or headliner, what is the trick to separating the rod that runs through the headliner from the mounting swivel bracket? I removed the set screw, I cannot see any spring clips holding the rod in place and I am unable to slide the rod out of the mount.
