'65 & '66 owners, please note, though the cars are very similar to '64, due to the transmission shift indicator, this procedure is slightly more difficult and involved on these cars.

It is real easy to remove the dash panel to gain access to the clocks on the 64 Imperials. There screws on the face plate I thing six or so. You can easily see them. Remove these & the face plate comes off. The FSM explains how to do it.
