i use them all zip products ,corvette america.corvette central,mid air america,chicago corvette,year one heaps.i normally wait till midnight and ring them direct,while i am talking to them i ask for a free catalouge and they now send me one every year.and dont forget oz corvette,kim byrnes,he is in sydney and could be a good local source.i am sure he will be at bella if you want to meet him.as far as e mails go dana hawk at corvette america to me has allways been responsive next day.but the others i have only dealt with them over the phone.;26
