How aboutt he positioning of that upper/inner pivot/knuckle thing, that bolts to the crossmember and locates the bushings. The bolts that secure it to the cross member aren't in line with the pivot, if you put it on backwards it could throw things off.

I think the lower/inner pivot that bolts to the underside of the crossmember is symmetrical.

I run mine with a moderate amount of negative camber, makes the wider front tires a little happier around corners.
