Why are you so insistent on OP not trying this option that has worked for many others? It's not reinventing the wheel, he's trying an option that has proved effective. Did you even read the 120 thread? The single spacer doesn't just lift the one side 1.5".
Why?! What you wrote doesn't make sense or have any validity too it. All I've learned from this thread is that you have no idea what you're talking about. If you don't have first hand experience with the topic being discussed, don't contribute wrong answers.
