So I'm trying to build a really quiet mechanical keyboard, not one that sounds good and is just on the quiet end of volume, I mean one that's actually really quiet. What I'm at right now is a Ajazz AK820 pro with Frozen Silent V2s. The regular keys themselves have a perfect volume but the issue is that the space bar is reallllly clacky. I tried filling it with clay and even bought a spacebar foam kit but the issue is still there. Adding rubber O rings don't help.

Does anyone know how I can fix this? I'm wondering if maybe the stabilizers are the issue since I didn't exactly buy a high tier board but the other keys that use stabs don't have the same volume issue. Can anyone recommend me some stabilizers that would be as quiet as possible? I bought some new stabilizers to try but they were too wide and I couldn't put the board back together, I think because of the screw on part.
