Just got my 4 link and going to mock it up. Wondering if anyone has any tips they would like to share for it is my first 4 link install. And the notch do I center it at stock ride hight or where I want my normal ride hight at? With driveshaft hooked up axel moved forward about a inch from stock hight with leafs in? Any input would be greatly appreciated before I start welding.tia
