does anyone have a recommendation for the replacement of the interior dash, rear window defogger indicator bulb, manual choke indicator bulb etc as to the bulb type? i've checked my local autoparts store and they had nothing. Does the bulb sockets have to be replaced? can i order bulbs from somewhere? replace with led's somehow? my interior is going dark and i would appreciate any advice. My cars and early 1974 260z. thanks!
