or swap, spacers 5x114.5

i have a set of ten mm (i think, never checked) spacers on the liner and the small nuts i have with them dont fit nissan studs because the spacers are off an evo i think. so there are big long nuts holding the spacers on. what im looking for is either ten of the small nuts for holding spacers on ora set of nissan spacers with nuts. problem is the wheels i have at the moment fit round these big nuts, but i have another set that wont.... so if anyone can help me thatd be great cheers.
