yes on the intake, thermoquad manifold,’71
On my '70 exhaust manifolds, the center port is divided. Not sure about the post '70's though.
I can't find anything on these numbers on the exhaust
The 953 manifold is 273/318. 1967-72 ABC
The other one is probably 73-up

Found this on the exhost....
I assume the 6 referenced is what looks like a 3 or an 8 in your photo.
4006741 exhaust manifold.
4006741 is a 72-74 318 a-body left/driver side manifold, should fit your 70 Duster but the price sounds kind of high to me for a 318 exhaust manifold, maybe if they were both 360 ones, would be nice to have a matched set on a 340

Does the drivers side have a bell or is it flat? 340/360 would be flat. Kim
Has a bell.
In reference to exhaust manifold with casting number 4006741.
Chrysler parts catalog number is 4006740.
Left 318 exhaust manifold for 70- 71 Abodies is 2951124 which supersedes to 4006471.
Superseded number may fit 72-74 Abodies with 318 engine but can't find any Chrysler documentation to that effect.
The reason it's not in any parts catalog is because it's a replacement manifold with a superseded part number.
