19mm converts to 0.748 inch... 3/4 is 0.750 inch... 0.002 inch is kind of a moot point when it comes to wrench size.
However, the OP is looking at buying a new drain plug and, I think, is more interested in shank diameter and thread pitch...
If the hex on the plug isn't mangled.... if the threads are in ggod shape..... and if the copper washer isn't near destroyed, try flipping the copper gasket downside up....
Now... here's a real "off the wall" suggestion... One visit to the "stealership"... Yep, there might be a little "pucker factor" when the price comes up... But one simple little visit to the "stealership" and you should walk away with the object of your desires.... No wishing, no hoping, no disappointments when you go to put things together again.
I can't speak for anyone else... but I see guys spending hours and hours to "save" a buck... Every hour I spend trying to save a few bucks takes me away from doing those things that earn me many bucks... It's called "false economy". We think we are doing good because it lowers our maintenance costs.... How many "billable" hours does it consume?
