no, the supra kit will not fit on the celica, but Erubeini makes a really nice celica gt-s kit. my brother has a 85 celica gt-s. as far as parts go, the places you can go are either LCengineering or Toysport.com. good luck with the car, glad to see another old school toyota found a good home!! i might be able to get you some parts. just give me a call and let me see what i can do.
