I've got a question. How did you make sure that the new front clip was correctly aligned? I know there are many hard points that determine the location with the firewall but the front suspension points are part of that front clip. Just the slightest misalignment of a few mm at the firewall might translate into a big difference in the location of the suspension pick up points in relation to the tub and rear axle.
