how do you know if you have a set of 12 slot genuine wheels? do they have ROH Australia on the inside of them or sumthing?
cheers.

Not sure if this helps but from the set of 12 slotters I had years ago on my cortina (suppose to be orig) the center caps screw on NOT clip on!

MR MAG here in wa have re released the 12 slotter which is from the original roh studded wheel, they look legit, they are studded and in the corrct silver margenta. i cant find their number but i think they are on the net.
p.s rudloc st, morley is the address

genuine 12 slot wheels will have R.O.H. stamped on the back, and they will also have the ford symbol stamped on the back , R.O.H. weels without the ford symbol are the same but not genuine ford. they should also be stamped 6JJx14 on the inside which is only visable when no tyres are fitted!!!!

Cortinas never came out with 12slot wheels and genuine ford 12slot wheels will never fit cortinas, and there are no genuine screw on caps, they are cheap copies probably made in china!!!
