R33Ade

Does anyone know if the rear upper camber arms on an R33 GTS are the same as fitted to an S14 Silvia ? As here in the UK the arms for an R33 are hard to get hold of, whereas the S14 adjustable ones are stocked at many places, and I have a felling that they are infact the same fitment Does anyone know ? Any help would be really appreciated Thanks Ade
