Mine split in half. Anyone know where I can get one? Tried Uniden, but they don't/won't sell them.

Search results - Uniden Bearcat Scanners, CB Radios, Accessories, and More! - page 2 place sells knobs marked for the BCD996XT but I'm pretty sure they also fit the 536HP models as well.
The item says it also needs the spring insert but if your knob broke in half, that spring steel insert is likely still on the volume control shaft.
I've never dealt with this company so I can't vouch for them but I have seen several other regulars here in the Uniden forums mention them as well.
I myself bought knob sets for my x36HP models from the same seller on eBay but not the glow in the dark model that
@iMONITOR was talking about. They are laser printed knobs and are generally easier to grab as the set also comes with a new function control knob.
Those eBay knobs also fit my older XT models as well as the 996P2 models.
I'm not sure why but when I ordered four black colored sets, they also included a full set of yellow and red knobs for the three controls that use knobs. I ended up using them for a day on an older 996T model but didn't really care for the red or yellow color so they probably live in my parts bins now.
I'm not positive I did get them from eBay and I may have found the same seller on Amazon but I think both had the same cost and free shipping.
