I installed the Bilsteins recently and there are a couple things you need to be aware of. The top stem is a little longer and there is not enough threads for he nut, so you'll need a slightly longer top bushing or use two bushings so the nut can be tightened. Second, it required all my strength to compress the shock to get it into place. Because Bilstein shocks do not have anything to grab onto, at the top of the shock, I used my socket wrench with a deep-well socket to go over the stem to compress it. My muscles were sore for the next two days. You can get a little more clearance by taking all or most of the weight off the wheels, that way you'll not have to compress the shock as far, allows you a little more room to remove the socket and time to line the shock up to the upper hole. Remember, you'll need to "charge" (compress the shock a few times--I put the top stem onto a block of wood and leaned into the shock using my body weight for the charging process) before you try to install it, otherwise, unless you're a body builder, you'll probably not be able to compress it while you're crouched under the wheel well.
