I got my Bilstien shocks from ORD because nobody else carried those special valved shocks in the 10" stroke length I needed. Once I went on their web site, and figured out what part number I wanted then I called them, and ordered over the phone so I could have the person that answered verify that I was ordering the correct shocks. I installed my shocks with the boot on top because with the boot on the bottom they could get torn by rocks and stuff.
