Are you looking to take just the track and put it on you fox seats or are you looking to take the whole seat and track from another year mustang and put them in?
That I dont know but if you find a track on ebay or somewhere just ask if they will measure the seat to track mounting holes for the dimensions and compare to yours. Sorry I couldn't help with that. now from what I do know all the seat tracks from 79-04 will mount into the car and 05 and up tracks will mount in the car with a set of adapter plates that I've seen on ebay and somewhere else.
