Anyone else struggle with the dse instructions and templates. They want to reference all their measurements off pinch welds. At least my car is all stock metal, but I am really stressing about making sure the 4 link brackets are dead nuts, and depending on what measurement spot I use makes a difference whether it's on or not. Also, they want to reference from my old axle center line, which I marked at ride height per instructions however my car was gutted out so, my ride height is different than stock. Maybe I am worrying too much, this is my first suspension job and I want to make it right, but with adjustable links should have some margin for error????
