Do they have an extrusion that goes up in the hole where the shock shaft goes through?I see what you're saying. You're correct, Bilstein doesn't include those when you buy the fronts...although they are manufactured. I had to buy mine separately. I don't know if that's part of the tophat or shock...but it doesn't really matter. Bottom line I put in new bushings because the tophats I used had them removed already.
