I had Tokico Illumina adjustables on my SN95 with the H&R supersports. If you switch up to foxbody struts, they will have more travel room if you want that, but I'd stick with ones designed for the SN-95.
Hit up Kevin at Performance Auto Sport in Central, they do Mustang suspensions all day long and can give you much more detailed info.
