At what point did the headlights with the larger bezel and upright position in the picture above change to the slanted headlights with the smaller bezel?
No change during production timeline at all, just the difference between US and European type of headlights.
The above picture was made before purchasing her in California. Here you see the diffenece of headlights during our change.

So she looks now.

Same procedure with the Tangerine, not the nicest pic of her at the moment but without the 1973 big front bumpers and with Europeam lights, all is reversible.
