5,75” to 7” headlight conversion

My recently acquired Mk10 has the small headlights. Apparently the 7” embellishers are not available, somI will find old ones and rechrome them if the Mazak isnˋt too pitted.
What about the lampholders and chrome retaining rings? Will look for those too.
What else do I need? Not much…(I have many lamps for both H1 and H4 bulbs).

Try AES for bowls etc.
