I'm restoring an FC ute at the moment - as a commercial it didn't come with indicators, radio, heater or chrome aroudn the lights. I am tossing up between keeping the original "no indicators" or upgrading. The one in the photo is an FE (56) so didn't have indicators either. A modern convenience then.
A bit of trivia for you - only the FE/FC Specials came out with door locks on the drivers door. The standards and commercials only had them on the passenger side. This was to allow those that purchased specials to enter the vehicle from the driver's side when the car was parked in a driveway. At that time it was illegal to enter a vehicle from the driver's side when parked on the street because it was a safety issue with passing traffic.
I'm keeping the driver's side door original along with the bench seat and 3 on the tree for nostalgia purposes but am warming the old grey up a bit with triple su carbies and a bit of head/bottom end work. No need to rush getting anywhere in an FC nowadays!
