Does anyone remember swing out/down aftermarket steps that were used on the high Ford and IH pickups in the 60's, early 70's. I believe they were marketed by the company name that produced them(like Myers Step). That's not the name, of course, I can't remember the right one. They mounted on the frame under the rockers and were pulled out /down by a pivot rod attached to the bottom of the door. Pulled back by a spring. I'm trying to find a pattern or a good picture of one.
