Yah, honestly, I've never noticed them in '67s. Kind of "rare" since they are only in A/C cars. So, I've never tried to remember them. But since it doesn't stick out in my mind, I would say that all the '67s I have seen were chrome...
Is the car in the picture a survivor or a restoration? I would only put weight on things found in an unrestored, unmolested, original car. I hope someone can help you out. I've only been "researching" my '68's options, etc...
