unless you want to drop big bucks into seats, fox body mustang seats are a almost direct bolt in swap. for a while I had seats from a peugot XR (I think), black leather, heated way better than the mustang for bolster, and super comfy, and got the pair out of a junk yard rip free for $30. I ended up selling them for $100 for hte pair, my seats are now on the roll cage and not on the floor so I have a set of $25 jegs plastic seats. not at all comfy, but effective.
