thanks for the tip Mitch (your tk is looking good by the way) I found my old def knob just need to clean it up. I was missing the fan knob as why i bought the set of new knobs. I only had one insert which is still in the old def knob. good to go for now. 1963c-10 I'm ok for now (until the fan one comes off) will keep you in mind, and thanks for the offer.
