Cowl tag X55 or X66

[dechev]

Thanks for the responses. Back when I purchased this car I was not aware of 'X' codes meanings. I liked the car, a convertible, it had the obvious BB heater etc. and looked like an original SS, lots of options, even had a rear window defogger. As I am not the original owner, the car may have been altered as back then all we were interested in was speed and ET and originality was unimportant. I do not have any documentation. I will take a picture of the trim tag and post it. It may take some time as the car has been stored since the early 80s with lots of parts in front and around the main body.
