The 1990 to 1993 were stronger then the early ones. I believe most late model Mustangs have a 3.08 rear
ratio. Alot of people take advantage of the overdrive and run a little lower rear gear, 3.55 seams to be popular. Here's a chart for the different gear ratio's http://www.mustanggt.org/gttranny.htm
