I had a pair of bags that came with my ’87 Daytona Shelby (my only new car) with T Tops.
I ran across the bags a few years after I no longer had the car - wondering what in the heck these things were (sense I’ve only seen them a couple of times before).
Not able to come up with a good answer, at the time, I discarded them.
Then, a couple days later, I had a hand meets forehead moment.
