That is a 69 style knob, often service replacement parts differ from factory installed.View attachment 24735 Mr sir purr, and don..Question I have a few of these complete kits,marked for 67/68, so as shown in picture,its has the knob there, but no defogger written on it, It seems a few of the 69 cougars I have stripped have had the defogger on their switch or mount plate. So my question as I'm taking it that Don would know this, why doesn't this kit have defogger written on the knob. I can open up some of the others and check too to see how they are marked. Hope this helps to clear up some of it, as this is a legit kit complete here,maybe its depends on what cars it was going into??
