Re: triangulated 4 link upper link bar question
That is a bad example. Usually the reason for mounting them so high in the front is so they don't hit the driveshaft.
I know if I had the option to mount mine lower, I would to make my instant center correct.
Parallel works but still isn't right. Even a parallel four-link from SD is slightly closer together in the front than the back.
A simplified generally-accepted way of doing it, is at ride height, if you were to extend an imaginary line forward from both bars, they should cross at about the front bumper.
