I’d advocate putting the clock knob next to the clock jack. From the original panel I see the hole next to it isn’t an LED as I thought but a push button. Is that hole big enough?
Also in the original the LEDs are above the Fill jacks… but yes, they could go further down. I’d normally use 5 mm but given the tight space I think I’d go with 3 mm here.
I’d change around the left-right order of the top knobs or the top-bottom order of the left jacks to make them match.
