Let's just make this super simple...SN95 axles, use SN95 brakes this will bolt on if you use the North Race Cars adapter bracket. Yes they are .75 longer, thus the adapter bracket.
North Racecars Brake Solutions Go to this site and you will see what I'm talking about. If you want to convert to the SN95 front brakes, you will need the 94-95 (ONLY) front spindles to do so. This will move your current set up 3mm farther outboard. Not that it matters, but the control arm is 1" longer on the SN95 cars. They also use a low friction ball joint, as compared to the fox body cars. Wheel/tire size will also play into this equation. You only have so much fender to squeeze all of this under/around. Fenders from the 92' and later fox body cars will have wider openings at the bottom to accommodate your choice of fat rubber. If you want to use the Ranger axles they will clip right in. The 5 lug conversion uses these axles with the corresponding drum to convert the 4 lug to 5 lug on the economy set.
