Thanks! I kind of felt they started in 67...I never knew about the horizontal mounted case, I have 7 verticals though..
The rack is made of a type of partical board /masonite...Good to know it could be 72.....I remember standing in front of one in 74 stealing lit..
I did manage to get a few more cases but all are of the Goodwrench era..Old dealerships are getting harder to find!
Thanks,
Steve
