Is the distance between the rear axle and the rear frame rail the same on both sides? Is it also centered from side to side? Just some measurements to take into consideration...
Here's a simple test to do. Jack the front up so the springs are not taking any weight and support it on equal height jackstands. If your rear end is still out of whack, it's not your front end doing it. Just a suggestion.
I don't really like it... :shrug:
I think the 2006 V6 grille would look better, but at that point you might as well have used the 67' light bar grille anyways...
I like the looks of the Mag Star wheels, but it's your car. If I were to change I wouldn't use a modern knock off of the Torque Thrust...
I'd get the original...
