Problem is that I don't think elongating those strut holes is a very common practice at a lot of alignment shops (sounds like a good idea; never heard of it until now). I literally took my old '89 to two different alignment places that "aligned" it, and I had problems with wear on the insides of the front tires both times; ruined two sets of tires in a years time
That leaves you the option of finding a shop that can do the alignment RIGHT with stock plates, elongating the holes yourself before bringing the car in, or getting the c.c. plates. I chose c.c. plates because I didn't know of the strut tower fix before now, and because there are some advantages to aftermarket c.c. plates; most notably the spherical bearing on aftermarket v.s. the rubber strut mount in the stockers which actually deflects/binds in hard cornering (if you are at all into corner carving, this isn't a good characteristic) as opposed to just swiveling.
