I have a question about which year 4Runner caliper can be used with the stock rotor. I know that it's the S12 or S12-8 (I have heard both and do not have one in hand to confirm which one it really is but it's NOT the S12W) but on one website it says '79-'83 yet someone on this board told me they used them from an '84. Is the website I have read incorrect or is this person simply mistaken on the year caliper he has?
