I think Celica ST162 rear is the same. I havn't found out if its true, but from memory its it.
Best bet is to take out a pad, go off to a brake place and say you have a 'Toyoda' and ACT really stupid. If they say Celica, say something along the lines"..........aaaaaaaaaa yeah, I think thats it..." and the guy at the counter should pull out his trusty Ferodo catalogue and try and match up the pad silhoutte to those in the book.
Your local Bendix stockist should be able to help The part number is DB283 and are available in Metal Kings, and standard compound. Also Ferodo stock them if your lucky enoough to find some, like i did once at Supercheap of all places??
