I do not know for sure but I think that 289 and 260 cars that were not used for competition there calipers were iron . These may have been used on other cars but I think they will be still expensive and if used will need to be rebuilt which in itself will be expensive. Comp cars usually use aluminum calipers and I am not sure if they fit on anything else. I believe they are Girling
