Getting the Instrument Cluster out of a 66

[usnabill]

Hello all,

I searched the forum and bought the shop manuals but I just can't seem to get the headlight switch disconnected from the back of the instrument cluster in order to pull the cluster from the dash. What I know so far...

-I can get the headlight "pull" from the unit by pressing a spring on the headlight switch
-I should be able to unscrew the bezel from the dash thus disconnecting the headlight switch

The outer bezel will spin freely, but the inner bezel which should screw from the switch is frozen in place. Am I missing something?

(It's a 1966 truck)
