Does anyone have a procedure for the removal of the driver (LEFT) side door lock mechanism.

I have disconnected the 4 linkages and removed the 2 screws from the side of the door and the single screw from the inside door panel side ... but there must be something else holding the lock in place as it does not want to move.

The Haynes Manual I have (1970 - 1992) is useless.

A video would be real cool if we have one somewhere.

Thank you

Paul
