Are you saying that a 1966 273 is different a later year 273/318/340/360?

Sorry, no. My bad if I misread.
The first two years are different. ‘64 & ‘65.

The attaching bolt hardware is smaller in diameter.
It also is drilled at a different angle.

There! I said it twice.

For the owners of the first two years of the 273, Believe it or not, disregard at your own risk. I’ll just say “I told you so.”
