RealOEM lists the same-named bolt for my 1997 1.9L. So I opened a box with a new Sensen strut to look at that third or top hole, and the hole(s) are slightly oval. So I now see that due to the range of movement in the oval, changing struts would most likely change the camber part of alignment. Especially if the holes in the car were also ovalized. The tie rods would adjust the toe-in part of alignment, but are not disturbed by strut replacement.

The APX Sensen video at on installing Z3 struts therefore has two omissions:
1. It does not mention the oval strut holes which affect camber.
2. The strut that is removed does not have a rubber bumper or plastic cover, which are necessary original equipment and fit together. The Z3 used for the video must have lost these in a previous strut replacement:
Bumper 31331092670
Protection tube 31331137932

Bilstein struts cannot use the OE bumper and cover, as they are designed to bump-stop internally and have an accordion cover.
