Hello everyone. I have a 1966 coronet it is missing the 2green lens for turn signal indicator.how do I get in the dash to replace them. Thank you

 

First drop the steering column / wheel down - let it rest on the seat, then remove the bezel screws, then pull the wiring plug from the back & disconnect the speedo cable, then pull it out some so that you can get to the alt wire to disconnect them. Then you have to split the two half's. Make sure to disconnect the battery first. Before re assembly I would re solder all of the brass pins on the circuit board for the wiring plug
You also need to remove the radio if equipped
