I used that exact piece on Randy's car. Bolted through the floor or a bracket on the "strap" end and the "j" end is made to hold a muffler clamp, http://www.delcity.net/store/Saddle-Clamps/p_798733 , to go around your pipe or turndown. Worked perfectly. You could also weld the strap end to the floorboard. All parts are available at O'Reiley's, Autozone, etc.
