This is a pic of a 66 or 67 GTO... The chrome on the door is not on my 67 is it GTO only or is it also on the skylark? Skylark
yep, optional. my Skylark doesn't have it, but my GS400 does. I believe it's called Belt line molding.
I have a set I have been wanting to put on my 67 for a couple decades, I will get around to it one of these days, bucket list
