Appreciate the reply. However, the knobs that were on my car, sure appear different, and look "factory"... attached pictures, show mine today. These are about 1 1/2" long, 1" dia on big end, 1/2" on small, with some concentric groves in tops. As you can see, the plastic has "rotted" with age.
Did check the referenced parts site. 2012 listing was about $30 each, didn't call to ask for current costs.
Would like to keep them similar to ones that came off, if possible. Think the color/shape look better (more "modern/period") than the round black ones. So, still looking.....hoping.
Again, thanks for the reply.
