72 Duster twister with the 275 horse 340 engine?

I read this:

The Duster seen here is Gary's second, a near-exact replacement that remains in its original, unrestored state, right down to the original tires. It's just as the day he drove it off the lot of Auburn, New York's Howard Chrysler Plymouth in 1972.

and I see a Twister hood treatment and a Twister-icon on the quarters...

Do you see a fender tag showing the "340" engine code WITH the code for a twister package?
