My only driver of the era is a '55 1st with the later '52 and newer push button exterior handles. I don't know how similar the the '47-'49 mechanisms are to that.

On my truck I decided the best answer might be to both lock and unlock the doors using acutators. But I've not done it yet.

I think the difficulty in controlling the locks is why most people change latches and pop the latch instead of control a lock.

I have the power lock and latch mechanisms from a mid-90's Cadillac that I've considered adapting. I don't know that these are the best choice but when I next chase this challenge I plan to figure out if that is an option.

It's true. I really don't do anything but browse the Internet looking for trouble...
