The years 1990 to 1993 ford use 3.50 gears was upgraded with stronger 3.35 gears sets by adding the nickel content. This was to make the gears hard and strong and to make the 2nd and 3rd gears decrease a little to give it more torque to the rear wheels.
It is not a direct bolt in, But if you know what you are doing you can modify it and make it fit.
the rear speakers can be removed by getting a 5/16 inch socket and loosen the bolts holding them in
