I can't realize what any of that is.?:?
If you have Microsoft Excel, you can download the zip file from the link below.

The light blue cells are the ones where you enter your data. Sometimes highlighting the cell will provide a brief description.
Basically, you're entering your vehicle specifics and link info and the spreadsheet will "predict" the resulting anti-squat numbers, etc. The numbers equate to how long your upper and lower links should be and how much separation your uppers and lowers should have at both the axle and frame ends. There's a science to it all and math was never my strong suit. If you don't get it close, your rear end can end up either jacking up or squatting on acceleration. You also need to control how the pinion reacts when the suspension cycles so the driveshaft doesn't bind and then there's keeping the axle centered under your rig, etc. FWIW, flexy suspensions at slow speeds on the trail don't necessarily equate to smooth cruising on the street. There's a lot more to it, and I'm no expert, but you get the gist.
Jake and other more experienced builders can chime in with more specifics. I researched it a while ago but didn't have the balls to go through with it! My 1-tons are still sitting in my shed! :-[
