Celica seats from the early 90's can be real nice, the GT seats especially.  I put a pair of charcoal grey GT's in my '84 SR5 Xtra cab 4x4, 3 out of 4 mounting positions aligned and I think the fourth will fit with a little tweaking and shiming.  I took the seats completely apart so I could swap the passenger foam sections to the drivers seat. The passenger side is always in a lot better condition than the driver's side. My "new" seats look super sharp, match my interior and feel like $600 aftermarket seats. I paid $100 for the pair!
