I was looking at jacking up Ruby with my floor jack and the only places to put a jack is on the wielded frame/body seams. I know this is where most new cars are jacked up from but their must be a better way. It seems to me that you could easily damage the seams with your floor jack. I found some rubber jacking pads on Amazon that have a slot in them for the body seam to sit in. They look pretty good to me but a bit expensive for a slotted Hockey puck. Anyone had any experience with these or what do you use when jacking up your car?
