The 1975-76 ACL cars that were shipped to Canada and US seem to be a year earlier than the oldest ACG 1976-77 cars that were available in UK.
That being said, My race car is ACL512U, and was built on 22 April 1975 according to the BMHIT document. I also have the VIN plate from ACL924U which I scrapped (it was a total loss and there is a picture in my album). The built date for ACL924 from the VIN plate is January 1975.
Seems like even at the very start of production the lower VIN number car (512) was built 3 months after the higher (924) number one.
What build dates are the early ACG cars then?
