HX Lowered Suspension

Need to change the shocks in my Kingswood so i figured i would put some superlows in it at the same time.

According to the usual place i get suspension gear from there is no such thing as a shortened shock in Monroe/KYB.

Any advice would be good, its just a cruise so i'm not looking to buy Koni/Bilstein like the Torana has
