My shower has a mixer valve capsule whose only marking is GOBO 21411. You can see it in the pictures attached below.
Thus far I know that "DANCO Cartridge for Glacier Bay Single-Handle Tub/Shower Faucets | Works for Hot & Cold Water Applications | Faucet Repair (10321)" does NOT replace it, as I bought it and it's bigger than the capsule. What is the right replacement part, or aftermarket part for this?
Googling tells me GOBO is Glacier Bay, but I have no idea if that's right.
Here is a picture of the shower faucet mount,
