aftermarket lower pullies work on regular f 150's
 

I'm one of those lucky souls trying to spin a Procharger D1sc at 10 psi of boost with the chincy 6 rib pulley system that is provided with the Procharger kit. My Vehicle is an 01 f150 4wd equipped with the 5.4. I see a lot of aftermarket oversized lower pulleys for 03/04 Cobra's and second generation Lightnings for sale on SVT forums and both of these mentioned vehicles run an 8 rib setup, I was just wondering if one of these aftermarket pullies would fit on the standard 5.4 setup as well. I was under the assumption that you needed a custom machined lower pulley to provide an 8 rib lower pulley until this popped into my head, anybody try this???
