The housings aren't any longer, its the axles. Supercoupe, Saleen fox bodies and Mark VII axles are 1.5" longer on each side. 94-98 axles will work for you. They are each 3/4" longer than stock fox axles. Don't use 99+, they are about an inch longer than fox axles. If you need to do the front still use the 94/95 spindles, the 96-98 will push the wheels out further than the 94/95, which isn't a bad thing at all, but on a fox you don't have room for that and a 9"+ wheel if thats what you are running.
