Official not...
But I found them somewhere, and a few weeks ago I found a '50 short bonnet MM, highlight, but from the time the lowlight was also in production.
See for pictures this topic:

I have 1 RH and 2 LH wings, not perfect, one grille, without the chrome part, but with old and new headlights.
I brought the parts somewhere for sandblasting, and painted them in a ground colour, to put them in the storage.
The left wings are both not ready for use, one needs complete welding, other has some bad weldings.
The right wing is an unused imitation wing, never mounted on a car.
What I have is this:[frame]

Because I cannot use all the parts, I have a lot now, 3 spare engines, an almost complete car, and don't have a Time Machine, it is possible to sell some of the parts.
My first Idea was to use a lowlight grille in my highlight car, but when I found the highlight grille with chrome insert, I was not so sure any-more ;)
I was looking only for the chrome insert, but found a complete car.
The previous owner bought him for the parts, took the centre pillar, and some chrome parts, and that was it.
In this car, the original inserts for the lowlight headlights are also there, and because of the price from spare parts, I am not sure to keep the car for restoration.
