Hard to see in the catalog picture, but looks like the “dish” of the wheel is more conical than convex.
The conical type don’t fit over the original brakes in the rear, but the wheels with a more curved center dish do just fit by about 1/4” of clearance at the drum corner.

Hard to do sometimes but always advisable to test fit a wheel before committing.
