You can see in the picture that the VHF and UHF knobs don't match. They're supposed to. The circular sections and number plates do, but not the part you grip. That's what I'm trying to swap.

You have to pry up on most or all of the gripper fingers on the retaining ring, that hold the number plate to the knob shaft. A bit of patience is needed.
Also, make sure that the numbers line up, with the tuner position. You don't want to put the retaining ring back on, only to find out that the numbers don't line up. There should be a keyway on the number plate, but you never know.
