I would go with the magnum one. Should be red for 69 I believe? Does your car have factory exhaust manifolds? If so are they HP or log? HP would have been a magnum and log style would have been four barrel IMO.
I’m sure other members will hopefully add more insight to this, but my opinion is Magnum. From how I understand it Dodge called it Magnum and Plymouth called it Super Commando. Here is some information I found. By the way as a side note, get a couple of them because I’m worried they won’t be sold much longer like the 440 ones. Those are no longer available and are going for $200.00-600.00.
Air cleaner pie tin IDs. What does it all mean?

With A/C? Then it would be 4 barrel.
