I have a set of Brainstorm low profile pop up headlights that fit an NA Miata. They came off a car that was turned into a spec Miata and have been sitting in my garage for a few years. They seem to be complete and include the instructions on how to install them on your Miata.
One of the light housings is broken but a replacement is $39.95 from GoMiata.com. They are also a bit rusty and have some peeling paint but nothing that wouldn't clean up. A brand new set from GoMiata.com is $$489.95 and I'd like $200 plus shipping for this set.
