I searched the forum for info in fitting central locking to pre 78 C3
Here is my version one, of how to do it
I would like to fit two actuators to each door have some back up and do away with the key entry

One actuator is mounted on the cover to access the door internals
the other will possibly be inside the door
Still working that one out.
I could go with coping the later 78 up idea for electric locking.

mod to actuation rod

assembled unit

Yup! Did this on my '77. Was pretty easy actually.

Works even better when everything is lubed up. :rolleyes:

Early C3 is easy as there is a large void in back of arm rest to surface mount actuator. My 78 had holes in the door from factory which lined up with Jaycar actuators. Is a bit harder to connect to door linkage as is on inside of door

I have a photo of a 79 door showing the rivets retaining the vette electric lock actuator inside the door .
I will mount an acturer inside the door and cut a hole for the acturer rod to allow it to attach to the vertical lock rod of the earlier C3
I was hoping some else had already don't that .
Two actuators give back up for failure protection
