I bought the chassis stiffening kit from Hall and I am 99%positive the main hoop was supposed to go in the engine compartment. It came with 2x4 box tubing to go in the frame rails and a number of other pieces to go in various other places. I got most of my other roll cage stuff from Chris Allstons Chassisworks. They send you a form to fill out and send you all of the pre bent tubing. All you have to do is trim it to fit.
