Original Motion window sticker?

[L34Pace]

Hi all, I'm working on a 68 RS/SS L78 camaro that has some race history at the "old" Wayne Meinert 1/8 mile track that is now Gateway in ST. Louis. The car was factory ordered for that short track with an M22 and 4.56 axel ratio. The original motor was not with the car when I got it and I'm building around another MQ camaro block. Here's the question, the body has 15k original miles and plenty of original docs but since the motor is gone I dont have a clue to what was under the hood other than from the factory. I bought the car from the family of the original owner and all I know was he knew Harrell and the cars only sign of modification is a pair of Motion stickers in the windows. These stickers are placed on the outside of the window not on the inside as I understand was original. I'm wondering if maybe Motion products might have been used by the owner? Or are these exterior type stickers later aftermarket and I should loose them? Any opinions would be appreciated.
