My best "I'm an idiot." story is something I did on my first car, a 1969 Chevelle, when I was 15 or 16. It had those bolt-on ladder bars popular in the 1970's and 1980's, and one of the front mounts had moved around and made a large hole where the bolt attached to the frame. So, I took the traction bars off. Note, these are not the same thing as the slapper bars used on leaf spring cars IN ADDITION to the rear leaf springs to control axle wrap & wheelhop. These actually bolt in IN PLACE of the rear lower control arms. This became very obvious when I lowered the car off the jackstands, and drove it about 50' before everything collapsed. If I remember correctly, the rear end rolled down, the driveshaft fell out, and the car dropped. Was able to put it all back together without any problems, and the only injury was my ego. 😳
