While Loren is right in almost all cases the Fox bodies have divorced Mac-Struts.
they can still be done without compressors, but you have to be very careful. actually the spring compressor for this application is a center post model, and unless the person is familiar with domestics they will not have the correct model. it can be done on a lift with a couple pole Jacks, or the special compressor. This is why we listen to people with experience. if you need help or want to do it here on the lift call me.

This job is much easier on a lift.
