NO longer looking ..found a cool car

Hi glad u found a car can I ask you advice as I own a so called 100 inch 68 champ car down here in Australia although unsure as now told its a sliver crown it has a 4.5 inch offset frame and at present has slicks for seal on it ,it does have a USAC vintage 69 sticker on dash and a 2015 Indy sticker as well, am hopping to fit some dirt tires for vintage racing here, cheers, Bob
