Chris My mate has a HK monaro, all original I believe. When it as at his mechanics a few years ago, some idiot scumbags broke in and ripped his tags off, as well as some chrome mouldings. From memory it was arount the time these cars were fetching stupid $$!!
His insurance paid him about 12K, But his heart was broken as no tags = No proof of its originality!!
He still loves it and is continuing to restore it slowly though..
I have seen an SS Torana at many shows with a blank Plate riveted over the Id Plate and on it he has engraved "Maybe" "Maybe Not"..
Im thinkin that when I take My Van to a panel beater or the like and know its gonna be there 4 a while.. My Tags will be in The Safe somewhere else!!
