Is there a kit to swap the stock 6 rib pulleys to 8 rib pulleys I looked for a while now and havent found anything yet. Can any people set me in right direction?¿? Also I am planning for a Procharger looing for an 8 rib on both the blower side and the Alt,W/P side.Or is there an alt and water pump 8 rib on the market? I heard theres another truck (expedition?)I forgot which car exacly ,but they have an 8 rib?
