I actually have a set of these on the shelf that I bought secondhand as part of a lot, ground back to metal and repainted in matt black hi-temp. I don't know whteher they were design for a Hilux or Celica, but they came off an RA60.
I could provide pics if that would help (and, shamless plug, they will be for sale)
What other modification has the 22RE got/is getting? Is it *worth* spending $700 for extractors on? Personally, I'd spend the ~$400 elsewhere on the car.
