Clausager says that North America 1970 and later cars had the dual filament
lamp at
the top, whereas earlier it was in the middle. Easiest way to check is to
count the
number of connectors down inside the lamp holder and on the lamps. The
locating pins
are also offset on the dual filament to try and ensure that the lamp ends up
with the
right filament on the right circuit.
