How do I find replacement glass for a chandelier sku #132-435 , vendor # 484-64

Any chance you know the manufacturer?

I can tell you if this is a Home Depot/Lowes type of fixture don't get your hopes up finding a glass. They are notorious for discontinuing fixtures and not caring one bit about replacement glass.

Looks like an HD SKU. Unless it is a stock item, probably not much chance of getting parts. They obsolete items like lights and fans after 2 years or less.
