Ordered parts to change out the struts on my wife's 2004 330i from ECS. The shock mounts I ordered had the P/N:31336752735 on their website, but when the came in they had the following P/N:31336769582 on the box. The shock mounts are from Lemforder if that makes any difference. ECS tuning wasn't all too helpful in clarifying, and I wasn't finding much online to confirm that the parts were the same. Just want to make sure I have the correct parts before I start tearing this thing apart. Thanks!
