My Apple Keyborard's ADB port is broken. The inside plastic came off and I can't get it to work. Where can I get replacement ports for it?

These are Mini DIN 4 sockets and are still readily available from places like DigiKey and Mouser. I’m not super familiar with the pin spacing Apple used on the keyboards themselves to mount them onto the PCBs, so you’ll want to make sure the part you use is roughly the same footprint and pin layout.
it's roughly the same as S-video, because I've seen videos of people using S-video cables with ADB accessories
Yes, S-Video is also Mini DIN 4. I'm thinking more the PCB footprint, not the plug itself. Different sockets are meant to attach to the PCB in slightly different ways which may not be compatible with the PCB in the OP's keyboard. For example, the one ADB Keyboard II teardown I ran across seemed to use a part that has 4 different through-hole prongs for the shield. However, the TE Connectivity sockets I saw on Mouser use a different arrangement of 3 through-hole prongs for the shield.
These are meant to take the stress of plugging/unplugging, so it is a good idea that the replacement can do the same rather than relying on the smaller signal pins for durability.
Beware that the port has to fit physically in the keyboard enclosure. And it’s a tight fit, better check out all the dimensions! (I once "borrowed" an ADB port from a 6200 motherboard to repair an AEK II, I was able to solder it just fine but it didn’t fit at all)
It should be the same part number as the one on the Macintosh SE Reloaded BOM, lemme grab that after Christmas dinner...
