That's EXACTLY what the seats I put in my '84 look like - same headrest, same color, and everything. (Hell, even the same stains.
) They're pretty comfy, aside from the fact that my driver's side has a minor case of the gangsta lean going on - I might "fix" that someday by swapping it with the passenger-side seat, so when Lynn sits over there, she'll lean over towards me.
I DO NOT miss those crappy LX seats that I pulled out. Too soft, too bouncy, felt like you were sitting on a friggin' trampoline.
My biggest gripe about those seats is those dang headrests are always in the way when I'm trying to look over to the right - it completely blocks the quarter window on a hatchback model. (On a notch, since the window is a little more broad towards the top, high-backed seats aren't quite as big of a problem). It was to my understanding from the dude I bought the seats from that they came out of an '89 GT. FWIW, these seats also have the power lumbar air bladder things in 'em, but I haven't bothered to run a 12-volt power supply to either of the seats to make that part functional.
The seats in Frankenstang's Capri came out of a '90 5.0 Mustang (LX or GT, I dunno) and are almost exactly the same seat, but they have the shorter flat style headrest like what's on top of the LX seats. They're not as pretty as, say, halo seats, but they're more practical because they don't block your view.
