I'll agree fully with R. Wagner: The Off Road Warehouse has about the best price, prompt shipping at low cost, and no sales tax if you are located outside of CA.
They are very helpful and eager to serve TDR members--remember to identify yourself as one and you'll receive a nice discount.
The Bilsteins are superior shocks. Other TDR members were most helpful to me in giving installation tips and guidelines via this forum.
Good luck, pal!
