My manual (August 1965) shows ivory knobs on the dash for the early 1966 models. Did the knob color switch to black at some point later that year or it's something that started only with the '67 bug?
Everything I can find says ivory stopped sometime in 64. It also shows that for 1966 they were a Silver Beige (Greyish). My unmolested 66 had the Silver Beige when I acquired 35 years ago and up to changing to ivory on the latest restoration. Also, black flat cushion type knobs came in 67.
Thanks for the explanation. Since the manual is in black/white I didn't realize that the light-colored knobs were actually grayish and not ivory-white as I thought.
Now it makes sense...
