nice old merc that one in your profile pic! i just received mail that you are looking for all 4 calipers fro a c36? i was part of the same thread since i wanted some bits myself but ended up buying a complete c36 as a donor car.
im in the uk but could post all 4 calipers for £350 UK pounds.
its a 96-97 model. is this the year you are looking for? the c36 im keeping is a 95 model and has different calipers.
regards
paul
