Seeking info on Export 69 R/S Z/28

[hubleyman]

OK you Whiz-Kids, let's test your Braintrust on this one. Twenty-plus years ago I acquired a Los Angeles built 69 R/S Z/28 from the 2nd owner who brought the car back from Germany. Over the years I have tried to determine if this was originally an Export car or just one that was shipped over after it was sold in the USA. The previous owner (Charlie Brown was his actual name) told me had to swap out the Kilometer speedo to a MPH speedo in order to get it registered in the USA upon it's return, but I have no proof of that.
I managed to save about 2/3rds of the Chassis Broadcast sheet from the gas tank and many codes are still legible (after many hours of careful resurrection).
So, are there any specific codes on the Broadcast sheet that would tell me it was an Export? I've heard that they may have used a different sway bar and perhaps other HD parts? I'm open to ideas here........
And just for FYI, it's a Burgundy, flat hood, white stripes, black deluxe interior car. And unfortunately, the original 302 was exploded on the AutoBahn.....
Put on your thinking caps please !!!
