Yes, I think it's close enough. I used a Dremel tool to grind away the backside of the rivets.
I dug up some Motorola knobs like the ones on my 12K2 and 9T1. There are subtle variations of the shaft type on the inner knobs. Are your knurled, flatted or split and knurled ?
As for what I'm looking for. The gold channel and fine tuning for a 7VT2 and a Predicta metal channel knob.
