Exh manifolds in an Early A...

Ok, assuming the steering clearance isn't a concern, does anyone know the outlet size of the 72-74 340 exhaust manufolds? Any difference on the pass side? The two I know of are on 318's. I've read that at that time, it was sort of a crap shoot as to what you got on the drivers side with the 318.

Whoops, never mind, it was already pointed out by @Treblig it's at least 2-1/8 and dag gum if google doesn't say 2-1/4" .
