1975 Dodge Dart Single Barrel Carburetor (225 Slant 6 motor)

I have a single barrel carb off a 76 slant six but I am in NB Canada and you are way over in Colorado, the shipping would cost way too much...I think. The numbers on it are GR-5147B, 4006613, 7363, 0616. All stamped on the fuel bowl and next to it.

Unfortunately those dont match what I have. Heres pics of the numbers on mine, for reference.
The second pics number is 6R-4573B
