'93-'11 Regular Cab short box, '93-'11 SuperCab are more/less identical, but you might have 4 used bolt holes in '08-'11s (or you can drill the holes in the frame flange and really secure it) and there are subtle difference in flares from year to year. You will want to keep your wiring/tail light as again there are subtle differences over the years.
'83-'92 RCSB and SC boxes will bolt up in exact same holes but panel lines aren't right.
'94-09 Mazda B series boxes also bolt right up, but the side panels are a little different. Then again, Ford used them on the Ranger STX package for a couple years, so you could call it stock.
Splash box swaps on too, you just need the flare side tail lamp wiring for your year, the correct tailgate, bumper and fuel filler hoses.
