I recently purchased a set of door struts. Unfortunately, the geometry of the replacement struts was not compatible with the original struts, or the car itself. The cylinder body of the replacement strut was about 5mm longer than the original Stabilus Lift-o-mat struts. I failed to notice this small but very important difference, and installed one of the struts, and to my horror found that the strut mounting post on the roof support was bent during the very first trial door closure. It turned out the cylinder body bottomed out against the mounting post, and because of the geometry involved, pushed against the post with a force of what I later calculated was about 2500 pounds. I would advize anyone replacing their struts to measure the new versus the old, to verify that you're not receiving one of these subtly, but dangerously wrong struts, unless you have complete faith in your supplier. I expect that any unfortunate soul who inadvertently buys and installs a set of these incorrect struts, and puts his trust in the supplier, is risking destruction of the mounting boss down the road due to stress fatigue failure. Personally, I find the sale of an improperly specified strut that is meant to hold a 100+ pound piece of metal in the air safely over my or my passenger's head a reprehensible act.
