Outer Limits 4x4 Board

Hi guys,

Does anyone know where I can get wheel locknuts from in Melbourne?
I'm aware there are genuine Rover items, but i'm tipping they'd be pricy!
Are there any aftermarket manufacturers out there?
I've tried the usual auto shops and 4wd suppliers and they all said "Not for Rovers" because of the HUGE size of the wheel studs.

Try your landy dealer mine in Newcastle were only to happy to sell me 5 for $5 as he had a bucket full from replacing steel rims with alloys presume they run a different nut it worth a try in melbourne

I'm actually after the tamper proof security locknuts, not just the standard wheel nuts.
I know Land Rover sell the security locknuts, but I was wondering if any aftermarket people made them?

several auto shops here in WA have them for around $20 set of 4
