That would be fine if they had a special jig with a templet to get the holes perfectly concentric, but doing them by hand, there'* no way they'll be perfect. :(

Actually, it doesn't have to be a perfect slot. The hole is there already, and really all you need is about 10mm at the very most. It would be pretty hard to cause the strut tower to go left or right to such a point that it can't be adjusted.

Those holes don't need to be machine perfect, as is noted by the oversized hole anyway.

Got my car back from the alignment shop yesterday. They did as the bulletin suggested, and my car is now flying perfectly straight!! I can let go ot the wheel, and the car stays driving straight.

Now that feels right, and I'm happy. :P

Good work.

Great news....glad that it all worked out for you!
