I have a similar issue. I spoke with CDan and as of a couple of days ago, Toyota does not offer a rebuilt front brake caliper for a 96. I don't know what the difference is between years. I do know if there was an alternative year, he is the one that would know. Doesn't answer your questions just confirms the situation.
