We´ve been throu this before...
Marchals did they use.
GT40 made ones...
Does not find them self on any other car.
Specially made, like 99% of the car was, or they ordered especially to "differ"...
123 x 233 mm did not use side lightning inside, just an H1 bulb.
Some used a head light with two bulbs...
Hi beam as an extra bulb...(with internally mounted reflective walls..sort of..to get the light were intended)
I wrote about this in earlier posts...
There are different Marchal´s, Cibié´s and Valeo´s who still share the same housing pattern.
Cibie bought Marchal, Valeo bought it all in modern times...
more or less hard to find these different lights.
Non is a easy find thou.
prices vary as well, of course.
Any body gives you different dimensions, they are out to fool you or is them selves uncertain...
Trying to help...
