Yep, as has been stated before, those wide rocker moldings were an accessory only, never factory installed. Only the Biscayne and Brookwood had the slender ones factory installed.
You also see a LOT of '63s and '64s with the '62 rocker moldings installed, which is wrong of course.

Hey Verne,
For the life of me I can not recall ever seeing a 61 with those mouldings, or even a car in some of those prolific PA junk yards that even had remnants of ever having them. Did you recall seeing any? I did see a few 60's that had the remains of some rocker mouldings, but no 61's.... I went digging skimming through all the old LGC magazines, (those were the days) not even a photo of one or any for sale in the classifieds, Not common at all, to the point that I never realized that they were offered, just never seen.
NYChevyII pointed out to me (privately) that there was an 58-64 Impala poster and Floyd Garret's 61 pictured in the poster has a set on.
I personally don't think that the 61's wear the rocker mouldings well, I am sure I am not the only one, besides being the first place to kick your feet to knock the snow off your shoes before getting in the car might have not helped the popularity. They probably look to good after one winter
