Also, if anyone is interested, this is the angle finder, it was not expensive and seems pretty repeatable, I’m only assuming it’s accurate.

When I first read this, it looked like ebartone was combining leaf spring technology with 4 link technology. No slight to ebartone, because there is a lot of info out there on suspension adjustment, good and bad. For a good baseline adjustment, set your adjustable control arms to the exact same length as the factory control arms. If your trans is in the stock location and your ride height is close to stock, you're good to go. Personally, I have never had to alter the pinion angle from stock on any of my GTOs.

Thank you for the suggestion, and yes, this is absolutely a four link so wrap is as everyone knows considerably less of an issue. The thing is, this is not a stock rear end, I just replaced the stock with an S 60. When I initially put all the control arms in at stock length, the result was a 0° pinion, that is level to the ground if you will. Now keep in mind there is a 1.5 downward to the back coming from the transmission. So in theory, yes, I could leave everything stock, but the result is pinion angles that really don’t agree with anything I’ve read. Of course, as you say, if all I was doing, was replacing the control arms, and I put them in at stock length, I wouldn’t have thought twice about this. But there’s more to it.
