So I am adding a clock to my dash in place of the Blank (75 Monza TC), I ended up with a real nice one to put in, but it is missing the adjustment knob. Does anyone know what the knob actually looks like? I found different ones that may fit it, one is a two piece item https://www.ebay.com/itm/1968-1982-C3-C ... 2913695971 , then I found a one piece https://www.ebay.com/itm/Chevy-Pontiac- ... 2912218727 . Got any ideas?
Thanks, Jeremy
