CIS air-box question - 2.7 -vs- 3.0

Is the '74 2.7 CIS air-box similar to the '80s model 3.0 CIS air-box? I know the first CIS air-box for the 3.0's used the large runners, I actually have a spare air-box with large runners and compared the two.

I am only worried about the runners on the later 3.0 lining up with the runners on the 2.7 and if they fit properly. (I am only using the air-box, not the CIS system as intended)

My 2.7 air-box was repaired by the PO but does have the POV. I wanted to eliminate any possible vacuum leak from a cracked box.

Thanks,

Never-mind, I should have looked in the new parts catalog before posting.

They are the same.

One part I have yet to find is a replacement o-ring for the POV.
