You said tell me what you know. I can do that.
Cut all the fingers of your hand at the 1st joint beyond your palm. Now try to grip/lift something. there isn't really a hook. Car will fall off. I've been there and done that, maybe before you were born. That experience Is what we go to the internet for, Right?
THIS IS THE WORST DESIGNED BUMPER JACK I HAVE EVER ENCOUNTERED! I'm old. When Hugh Robbins opened his first tire store, He had no choice but to use the jack in the customers vehicle. Google Him or Robins Tire Greenville SC, Easley SC. Chit went sideways, I ended up working at Robbins Tire in Powdersville when I bought our 1st 67 fish. Hugh told me, "Don't ever use that jack. It's a long story and I can't type it all.
If its a trailered show car looking for restoration points, I just might sell them the OEM jack but... I would first stress the heck out of... "Don't use it!"... (I'm not looking for parts or money anymore).
But hey, you're not me. You could sell all of them to the unknowing and reap the rewards.
OK, some of my story does include recapped tires. If you would like to hear it all PM me. Just know this, I would throw these bumper jacks in the scrap bin before selling them ( I already said that didn't I?). Good luck
