This is the best category I could think of for the question. My apologizes.
Im trying to replace my jack on my two axle car hauler. the new jack is top wind with 3 screw and nuts o secure it to the tongue. it has a removable shoe on the bottom. The old jack is top wind with 3 screws and nuts but the shoe is welded on. I don't know a way to get his off unless I saws all it and raise it up and out. Is this true? I'll try to upload 3 pictures of it.
