Basically how it goes is the supplied bracket mounts to the pinch weld on the firewall, and the stb mounts to the bracket. When you go to put that plastic trim piece back on you'll have to trim it a little. What you do is first mount the bracket to the stb, then set it in the engine compartment to mock fit it so I could mark the locations to drill through the firewall pinch weld. Then drill the holes... Mount the bracket (flat side facing the firewall), then the stb to the bracket. Then drill the the shock tower mounting points. You'll probably need to jack the car up on either side so the tires drop out of your way so that you can reach up inside there to put the nuts onto the studs coming down from the tower.
