these luggage racks were not fitted from factory they were dealer gm options back in the day,fited to the cars after they recieved them from the factory by the dealer ship,they are recognised by the ncrs people aswell.personly out of the 2 vetts the blue 71 for me is the standout 1,i guess it all comes down to price and how much needs to be spent on them to bring them up to scatch ,if at all that is,are they both LHD?how good is the interiors?allso the best thing is the aussie dollar is very high at the moment so if you need to buy from the states now is the time.keep us posted please;ay
