This is a DIY kit that uses your existing rear mounting block. Made to save you money while supplying a quality kit that you can finish on your end. It comes NOT WELDED as a parts kit. The parts are cut, cleaned, formed. The tubes are cut and beveled on the ends. Grade 14.9 hardware is also supplied. You will need to cut your rear block off flush and clean to be reused. If you do not have fabrication experience and can not do the finish work on your own I do not suggest getting this as there are bolt in options on the market already.
