From the looks of drawings i found online, the upper A-arms are on shafts with the shafts bolted down with vertical bolts. So the alignment method of adding or subtracting spcers behind the shaft won't work.

You could slot the holes to gain more adjustability. It's been done a lot on MacPherson strut upper bearing mounts, although they don't see the forces that the shaft holddown bolts do. Still, you should be able to make some changes.
