I have read that SN95 axles are wider. According to Matt at http://www.svo73mm.cjb.net./ Check out the wheel fitment page, because the SVO/Lincoln Axles are different from the GTs. "SN95 axles (1994-1998 Mustang) are 3/4" wider per side than the stockers". I am unclear as to whether the axle housings are any different. It appears that the differences in axles are due to the use of disc brakes.
