RV Repair: 1995 Gulfstream Scenic Cruiser Headlights, gm ford, market suppliers

Question
The headlight lenses on my scenic cruiser are clouded to the point of not being safe to use.  These lights do not use sealed beams, rather a capsule bulb.  It also appears that the entire assemble must be replaced in order to get a new clear lens.  Can you tell me what vehicle these assemblies are from?  Mine have Hella numbers on them but nobody seems to be able to cross reference that number.  The factory tells me they bought them from a "supplier" in Michigan but that is all they will tell me.  I can purchase new assemblies from the factory for $320.00???

Thanks for your help.

Manufacturers shop around alot for head/tail light assemblies and that can be a pain for us. They buy from GM, Ford and Chrysler as well as after market suppliers.
There should be a DOT number on that lens that would help the right person.
I have had good luck with the Plastic Lens polish to bring foggy lenses back to clear. It takes a little work but they turn out great.
I'd try that first before dropping big $s for new
