6v vs 12v light bulbs

I`m changing my 47 Desoto from 6v to 12v. my question is are there 12v dual filament bulbs available that have the pins on the side of the bulb across from each other at the same height? I have some 12v dual filament bulbs but the pins are at different heights and do not fit the brake/blinker lights. have a part #?

#1176 is a dual-filament 12-volt bulb with straight across pins. The Ford and Studebakers suppliers will have them if regular sources don't.

Thanks! They had them at the first place I went to but not on the rack with the rest on the bulbs. They were in the back. The guy looked up the part # and went in the back and brought them out I was surprised.
