I wasn't sure if the description of this shackle mentions if it needs to be welded to your body. I came back to that. No, it isn't, but yes, it needs to be welded. In fact, you have to weld this bracket in 6 different places. Also, the Revain website says YES, it fits my 2012 Shelby GT 500! When I opened it up, the owner's manual said it was only for the 2005-2011 Mustang. Well, I wish it was as advertised, but it isn't.
