Need discontinued hubbell lighting parts

I need covers for several recessed hubbell lights in a house I am working on. I contacted a distributor, and was informed that they were discontinued, no parts available, but I figure someone has them lying around somewhere, its just a matter of finding that person
The light itself is Hubbell HMUP5A
I need 4 of the part 35 203 YC which is the cover for the light.
If you know anyone who might have these, let me know, I don’t want to have to tear out lights unless absolutely required.
Thanks in advance.

I could look but wont dig thru my old stuff trying to read P/N.
You sure it wouldn't be better to replace the whole fixtures? You might get a nice IC rated unit that will allow you to insulate over it completely. Back in the day, you may be able to spot the marks left from the stone tools used to manufacture these museum pieces, energy was not an issue. An open fixture that left a hole in your ceiling membrane for heat and AC to get out wasn't seen as a problem.
Most old fixtures wouldn't let you put insulation within three inches of them. So a holes collectively the size of a golf ball and an uninsulated section. You might as well post your credit card numbers on the front lawn. With a modern sealed IC unit you get a good, usually not perfect, seal and you can stack up insulation so no more gaps. Much more efficient.
Failing that be aware that many of the better made trims are compatible between brands. Drop the can and take it to the distributor. Test fit trims to find what works. Avoid the cheap imports.
Cans and trims are rated as to what lamps, bulbs, are allowed. A matter of limiting heat buildup. Generally tighter and more enclosed trims and cans demand lower wattage lamps. Roomier and better ventilated ones can go a bit higher. Most cans have a label laying it all out. After ten years the labels are cooked off, destroyed or defaced so the manufacturers catalog is the guide. After twenty years you wing it.
With ancient cans and a trim from another company there isn't going to be any official guide. The best you can do is find a similar fixture and trim and use it as a guide. Be a bit conservative and be aware of the signs of overheating for a time.
