Here is the link for the picture. I am talking about cutting off the end from where the threads stop and down. We would recap the end of it, and weld on the bracket to fit my car. The top we have solved. It's just the bottom we need info about. I have a friend that works at a machine shop, and he's going to take them with him to do all the cutting and welding on them.
