Slant header ID?

These are the old Mopar/JR headers and are 6 into 1.PhotoView attachment 1715733435
Those are the Hooker Slant headers I would say. Looking at the #6 tube they look the same as the Hookers that I bought for another project.The ones I have are for a "B" body. The "A" body have that same long tube on the #6 that kinda comes out straight from the flange then turns down. My 2 cents.
Also in the photo (67 Dart) the engine mount bracket faces more forward than the Truck.I never looked to see if the A and B body Hookers have the same part number.
Wish mine were coated. Nice.
