Need to know the local for the power switches in the door panel for a 68 convertible. Got factory switches and power gear to go in and cutting new door panels. Do not want to mess them up. Info I could find said in line from the door arm rest under the vent window crank for the lock 1/4 inch over for the window in front. Rear 2inches up from chrome strip centered on the ash tray. Is this correct? Please help.
