I registered just to say that I got the ones from autoillumination (7443 bulbs) and they DO NOT FIT. I was the one on stangmods that said those don't fit either. I haven't tried 7440 bulbs so I'm hoping they work.
What exactly do you mean by not fitting??? 7440 and 7443 are identical sockets. The only difference is that 7440 has only 2 wires (being single-filament) and 7443 has 4 (dual filament). There is absolutely NO distinction between the actual plastic socket.
