However having trouble finding Depo housing, I see Depo lights but not really housing/assembly, is there a website / resource I can check?
Just search eBay for "Depo headlight 1997 Land Cruiser":
Headlight Set Crystal Clear For TOYOTA Land Cruiser 80 1990-1997 | eBay - https://www.ebay.com/itm/323978798784
You buy the whole headlight.
