Did these things actually exist on 66's like on the red SS convertible flyer i've seen so much of??

I bought my 68 off a old lady about 80 in the shade, its true . and it had a luggage rack on in . bright yellow with black stripes .the rack is in the shed because all me mates bagged me out about having a cloths line on the back of my car and a couple of other stupid comments . i'll put it back on one day to carry the esky full of beer around when i retire :beers:

I can't remember ever seeing one on the street.
