Looking for large diameter steering wheel

I just bought a '72 Scamp with manual steering. It has the original steering wheel that also came on the power steering equipped cars. I'm looking for a larger diameter wheel (15 in or so) that will fit onto the column without any adapters if there is such a wheel. I live in a city and have to do a lot of parallel parking. Maybe a wheel from a B or C body. I'm not sure what will fit. The car has a tan interior. What have you?
