Not sure if there is any market for these, but I have a set of OEM calipers from my 99 SR5. They are stamped with "S13WM" and my truck came with the 16" wheels from the factory. I have these as a result of doing the TBU but thought someone might have a use for them. They were working fine when I took them off last week, but I would recommend a rebuild. Some the dust seals are a little worn.
PM me if interested.
