Need 15"x5.5" Steel Wheel

Hello all. I recently picked up a set of 15" wheels for my 73 Dart. Once I removed the old tires I found one of the rims is different from the other 3. I need a Kelsey Canada 15x5.5 plain steel wheel to match my others. Condition is not important as long as the bead will seal. If any other information is needed I can to get as much as I can off of the wheels. There is no part number but it is OEM. Thanks.
