Amazing, like a lot of other folk, I thought I was well into the minority for these bloody awful things. I had them on a couple of '02s I had back in the '70s. What a damn nuisance they were. Unless you clamped the living daylights out of them, they would fall off, or one clamp would and the thing would swing to one side. They never did stop mud getting up on to the ledge at the bottom of the rear quarter panel where it was rust prone. What a useless invention; not surprised in the least that they are NLA.
So, having said all that, I wish I had a few dozen pairs to sell right now. I could buy a couple more parts cars then.
