Harbor Freight Jack Stand Recall

it's not the width per say, mine are about the same. it's the narrower board on the bottom that i don't like. i've been in enough earthquakes to know how easy it is for something to jump to the side a couple inches, and in a case like that, slide off the boards. you're in WI and don't have that concern :)
If I still lived in Northern CA like I did 91-02, I would be digging a pit to park the car over in order to work under it. Car doesn't have anywhere to fall. But then I would risk being buried alive by a cave in during an earthquake. Just can't win. Nothing is 100% safe.
