Let me find my rear lenses in my garage and review it. Not sure whether I used the oem housing and added the modified miata lenses or just used the miata housings too. I'll chat with Jason about this. If oem lenses have to be sacrificed in order to make molds for production, then I'll volunteer mine. I'll post results later.

FYI, the miata lenses will work with the vx housings. The internal housings just need to be trimmed in order to sit flushed with the housing. However, if you look from the side, you'll see that the lenses slightly bow out past the center about an 1/8" past the housing. Not really noticeable from a couple of feet away. But if you prefer that perfect oem fit, then getting molds made would be the ticket.
