VX Commodore sedan mushroom base wheel nuts, where to purchase

[NeddyBear]

I'd like to purchase a set of the chrome, mag wheel nuts to suit a VX Commodore which are going on a set of the VE steelies and I'm told they must have the mushroom base.
I've tried our 4 local tyre places and they can't get them and not even the Holden dealer has them although they do have them for the modern Holden Rodeo and they do screw onto the VX Commodore studs but I'm not sure if they have the same thread pitch.
Does anyone know where I could purchase 20 of the chrome nuts as described above.

they still make them and are readily available from holden.
but yes, the rodeo ones are the same thread and fit fine, i use them on my VX

Thanks Boonz, I'll go buy one Rodeo nut and take it to our local bolt place to see if it does have the same thread.

it does, its metric 12 x 1.5 pitch

I went to buy the one nut and Holden wanted $29.00 per nut so I went over to Repco and they wanted $26.00 for 10 so I ordered 2 lots of 10.
