A while back I was searching on here as to whether or not Bilstein had replacement bushings and saw a couple people had confusion on the order of installation.

I called Bilstein and was able to order new upper bushings and they also sent a diagram showing the order. The a-arm goes in between lines 3 & 4 (counting upwards or downwards doesn't matter) on the diagram. Hopefully someone might use this info in the future.
