Wheel Track Alignment
My 99s wheel track is out, the left front wheel is 13mm closer to the front of the wheel well than the right side, measured from wheel centers both sides, can a wheel alignment correct this, with 19" front the left rubs on the inner when turning right.

The thing is that the A-arms mount both to the subframe and to the frame rails. So if the subframe or the frame rails were somehow twisted, then the bolt holes wouldn't match up. If BOTH were twisted - and I don't see how that could happen without causing a host of other problems - then maybe.
Can you take pictures of both sides?

No, he didn't say that...
He said he measured from the centers of both front wheels, to some point in the wheel well.
You're correct, however, that he should "wheelbase" the car, by measuring from the center of the front wheel hubs to the center of the rear wheel hubs on each side of the car, then comparing these numbers. However, that can get tricky, unless you have a way to get the front wheels both pointed straight ahead, and at "zero" toe.

its probably the engine cradle is moved forward or backward to far on one side I had the same problem. Mine was to far to the left. The left wheel was out 1/2 inch on one side and in 1/2inch on the other. Dont take ti to the dealer they wont know how to do the job correctly. I went 4 times 3 different dealers. Finnaly took it to euro tire for a custom alingment. Car drives strait as an arrow now.

The cradle should be aligned with dowel pins unless someone messed with it.
The ball joints on the lower a-arms can be moved forwards and backwards by moving the arms on the alignments cams.
I'd say do some front to back and triangulating measurements between the front and rear subframes. Then, look into shimming the upper arms and then adjusting the lower arms to move the wheel back if the subframes are in the correct locations.
You may end up with the wheelbase different on each side of the car to get the wheel in the correct location in the wheel well. The inner fender structure might be glued on a little out of place.

Also don't forget the whole front fenders and nose can be moved too. The car could simply need all of the mounting bolts for the front nose and fenders loosened and moved forward slightly on one side of the car.

I've had the rear cradle out a few times. There was not 1/4" play in the dowel holes like you're indicating on the rear.
