also does anyone know where i may find the original Rockford Fosgate sub to fit under the rear seat, or is there a company who makes a sub/box to fit?

Yukon gear sets are, in my opinion, the best gearset and the easiest to setup. I work at a tranny rebuild center and our other shop does a lot of gear work.

Yes there a 9.75 gear. I've used pro5.0 and ford racing gears. Both were really easy to install. Alot of people prefer ford racing because there cut on the same machine as the factory ford gears so they seem to install better. As for the rockford box i looked everywhere for one. F150online and f150forum usually has one for sale if you can get tk it before someone else. Are you needing The pads or rotors? Stoptech sells the rotors. Saleen sells the pads for $200. But you can just buy late model excursion,f250-350 pads there the same thing for around 45 for a set of ceramic pads.
