NOS 340 360 Exhaust Manifolds

Right, so the Pass side is correct for a 340 only

But it will work for 74. The date will be wrong is all. That is if the first number is a 3 in the date. But if it’s a 9 it can work for a 74. For 75 I know the drivers side has a bell on it like the passenger side. Kim
