I would say it's the real deal. This booster SHOULD NOT have the "Delco Morane" stamped on the front cover. That should confirm it. Over the years, many have sawpped out the front covers.
You are so on the money Jerry!
That is exactly the case, no 'delco moraine' stamp anywhere.
Your comment has precisely answered my next question regarding that stamping, as I know for almost certainty that this is the original booster to the car.
As for determining the year, is 9078 just a sequence number that is known to represent 1968?
What would the numbers be for 1967 and 1969?
Many thanks everyone for their input
