I recall them, but never could afford them..either to buy or build.
Trim items I remember and had some examples of.. Fender skirts, curb feelers, Moon hubcaps, spokes, continental kits, sun visors, mud flaps,
and fox tails.
In fact, a few years ago, I shot a fox with my .17 HMR and acquainted my grandson with the old fad of attaching a fox tail to the antenna.
I gave him the tail and he affixed it. A couple days later, it was stolen off his truck while he was at work..
I did shave the hood on my 1950 Studebaker Champion starlight coupe....and I did an engine swap..replacing the 4cyl engine in a Jeep wagon, with a Studebaker 6 cyl.
Just a few things which may bring back memories...like the garter hanging from the rear view mirror..in those days the garter was more often
presented, rather than taken..
