gen 7 sports pack alloys help

[mart77]

i've just bought a set of 17 inch celica alloys off a gen 7 celica with six spokes and centre caps.i cant seem to find the nuts for them anywhere.does anyone know what they are like or where to get them as the jap spares place by me was well blagged when i took them to them.they are going on my 1995 gt.the ones off the original alloys are too long so i cant get the centre caps on.thnx
