I will have to send the $35 dollars to PHS to find out what it means..The only reason I traded the rear end for the car was because it had a real 1969 trans am spoiler in the back seat.I didnt know about the B80 Code on the cowl tag until I got the car home...I thought they located all the convertible trans am made? Then when you read other info about 1969 trans ams they say they made more then the 697 cars.
