Oddball keystone jacks

I had Uverse installed several years ago. As part of that operation, they replaced the wall plate & connectors I had with their own 4-hole plate and keystone punchdown jacks for (1) Uverse signal in to RG, (2) ethernet out to the rest of my house, (3) phone line out to the rest of my house, and (4) blank keystone to fill the last hole. A year or two ago, I pulled another ethernet wire from another location, only to find that the keystones they sell at Lowes, Home Depot, Amazon (pretty much everywhere!) don't fit into the AT&T plate. It appears they've taken a page out of Apple's book and chosen a (Edited per community guidelines) standard to make it harder for others to follow their work. I can't find a useful part number on any of this stuff, and my online research leads me to a site in Australia! My question is simple:  are there places that sell keystones that actually fit these oddball AT&T wall plates?
