Sometimes the only the left brake light works, other times the right and other times both. I've checked and in fact added additional grounds to the sockets themselves.
I suspect the problem is in the steering column associated with the turn signal operation. Work done by others when converting from column to floor shift (automatic). Hazard lights work but switch will not stay on.
Am I correct in my assumption?
Looking for a rebuild kit.
TIA

How did you add additional grounds to the light sockets?
First place id look would be the connector on the steering column. There is a feed from the brake switch ( should be white wire) that runs to the connector on the steering co!umn. Might want to check that for something amiss, such as pushed/ bent connector or damaged wire.

Are your turn signals functioning correctly? If so then that circuit should be good and shouldnt be anything wrong inside the column.

Do you have a reproduction wiring harness for your tail lights? I am fighting a similar problem on my 65 Impala, and I can wiggle the bulbs around in the socket and make the lights work (or not work). I think the bulb sockets in my reproduction harness are poor quality. It's frustrating.

well if they are connected like the 69 Chevelle they get there ground through the metal prongs that extend from the socket and hold the socket to the body. Sometimes those are not making a good connection, either through corrosion or just prongs not contacting solidly. If one can wiggle the socket and light cuts in and out the prongs should be inspected.

Just realized you probably already know the above.
