Csp Wheel Bolts / Studs?

[waltz19]

Looking for some help.

I bought a used Csp disc kit from here a wee while ago.

I run old 60s / 70s AEW wide 5 alloys and it took a while to find the correct stud kit.

The Csp kit I got has studs fitted but my nuts will not fit them.

Is it a case of buying new studs?

Thanks Alan
