Are the "Warning Light" housings available as separate / aftermarket parts?

Most or all of the eight warning light housings (e.g., items 3, 6, 38, etc. in the diagram below) on my 328 are bad. Some are worse than others, and only a couple are truly reusable. It looks like most of them are available new at various prices, but it also looks to me like the housings (the two black parts in my pics below) are the same among all eight of the lights.

Are the housings available separately anywhere that anyone is aware of?

Unfortunately, I have yet to buy an injection molding company. Your reproduction looks really good! I don't suppose you have seven or eight extra?

 

Yup - I'm now seeing that most of them aren't that expensive, though for all eight, it does add up. I think that by pure coincidence, when I'd originally checked to see if any of them were still available, the one part I used as a test case was a high priced one, so I thought I'd post here.
