Has anyone ever seen this? I'm trying to update the hardware in my bathtub, and the tub drain insert has no crossbars. An identical bathtub in the other unit of our duplex has the same thing, and the dome cover screen has this v-shaped clip that, when inserted into the drain piece (which the opening is 1-5/8"), holds the screen on with tension. Any clues as to where I could find replacement parts for this cover? I'd love to just use this one, but it belongs to the other tenant.

I would also love to just install new waste and overflow trim pieces, but the drain opening is 1-5/8" with a fine thread - all "universal" trim kits that accommodate the wide opening all have a coarse thread, and it won't work, hence my dilemma - I'd have to replace the entire waste and overflow system, which means tearing into the plaster walls because there isn't an access panel. Ugh!
