67 and up slant 6 needed

Is there a way I can verify this without actually looking at the crank register? Casting numbers?

I did a rebuild on an early 67 Barracuda 273/904 and the convertor nose/crank register was the smaller, early design. Not realizing that this 67 application had the early design, I bought a convertor from Mancini and it was different. I'm not sure if this was because of the early build date though.
