Pullies and Timing Adjuster

[RabidPony]

Ok, I know that the stock crank pulley acts as the hamonic dampner for the 4.6 engine. All the Underdrive pulley sets I see have to be mated to the stock crank pulley for the dampner and with this setup you ca't install a timing adjuster. Ok, who makes an underdrive pulley set that doesn't need the stock crank pulley? I want to do both and one or the other won't cut it for what I have in mind. I already have a Steeda timing adjuster on the car and a set of Steeda pullies sitting in my garage (minus instructions). Any ideas or pointing in the right direction would be helpful.
