I have a chance to buy some nice leather seats from an 05-09 mustang. Does anyone know if they will bolt up to my 04 fx4 supercab 60/40 tracks?

 

I just did this mod on my 04 Supercab with some 2019 mustang seats I picked up at a junk yard. Short answer is no, they won't fit your existing tracks, but if you're half decent at welding, you can fab a bracket yourself. It's not terribly difficult. Even if you suck at welding, you can have a fab shop make a mount for the seats for not too much. If yours are heated and cooled, I know how to make that work too.
