17、riginal jack was so slender, that I didnt dare creep under the car when it was lifted by this jack. There was no space for me, anyway! The floor of the car was badly rusted, because the car had been effected by some sewer gas in the garage. I had to cut large sections out of the floor and cover them with new steel plate.,
