Air Grabber air cleaners

[Ghoste]

This is actually for a 72 Road Runner restoration that a buddy is doing but there seems to be answer here for most anything you can think of, so...
For a 1972 Road Runner with single four barrel and Air Grabber hood, what is the correct air cleaner lid, large oval or small circle?

My brother had a '72 Road Runner back in the day, it was a 440 4bbl automatic Air Grabber car with the large base/ small element and lid. I've seen other non-6 pack cars with the large lid but I don't know if they were "correct" . So to answer your question definitively, I can only attest to the fact that they did come with the small lid but I can't say they didn't come with the large one as well.

Okay thanks, it's a start.  He wants it to be correct so I guess it's the burning local Mopar question of the weekend around here.

round lid on all single carb applications 1970 and later

Even 1970?  Cool and thanks muchly (didn't know that about the 70's).

Yes, all single 4 barrel cars with airgrabber  were round lid from 1970 thru 1972

1969 the first year for air grabber, is an oval lid regardless of carb

It should look like this:

Very purty there sir

There is a difference in the base for the 440 and 383.

Do you know what those differences entail?  (mostly just curious)
