Roadmaster Sedan Wheelhouse question

Are they the same as the rest of the B cars? I was given a pair to replace my rotted ones for $20 but just want to make sure they fit before I tear out my old ones.

The sedan wheelhouses are slightly different. They have a flatter opening around the wheel, where the wagon is, for the most part, circular. They may be able to be massaged to fit if the overall length around the opening is the same, and the bolt holes are the same. 91-93 wheelhouses are different from the 94-96 parts. The mounting holes are different for the accessories, and the large lower hole behind the rear of the tire is at a different location. I have not tried to use an RMS wheelhouse in a wagon, so I can not say they will just bolt in. They look like they can be made to fit with the only difference being the shape of the wheel opening. For $20, I would try reshaping the wheel opening by comparing it with the wagon shape. The metal is fairly easy to bend by hand, or with a hammer and dolly.
