Wheel Nuts!

Anybody know what part number I need for a wheel nut with a larger stud? I just replaced a wheel hub that came with studs pressed in, putting the tire on I found out the studs are larger then then nuts I had, so I ordered part number 576103, they arrived but hang on- they were the same size as the others. doh!
(I did search, but couldn't find a good answer)

Series 2a 109'
Thanks

Hi the awnser is that seres 2 wheel studs are different they are a 15/16 nut and the seres 3 are a thicker stud and is a 1 1/16 nut and if you go on to paddocks they actually say 15/16 or 1 1/16 nut for series 2 or 3

Just went to paddocks website, and 576103 are 1-1/16" , the ones I want and thought I ordered (from another vender), must have sent me the 15/16ths by accident.
Ill try paddocks and see what happens.
thx
