Arwyn, Richard, thank you!!! It really is one of those things that you know or you don’t. I’ve got some penetrating oil soaking in it now, will give it a day or so to work it’s magic. Hope I can save the knob- I see repros all around but only in black or ivory. Never seen the brown version except on my car.
I’ll let you know how removal goes, and final pics once the heaters finished.
