Educate me on rim blow steering wheels

I have seen a few rim blow steering wheels on Darts. I really like the way they look. There seems to be a company that sells reproductions ones on ebay from time to time but only the steering wheel. What else would be needed just a cap and adapter? Did they ever come factory on Darts? Does the E body adapter work on A bodies or does some one make reproduction cap and adapters?


I'm liking them and may be in the market for a decent looking driver rim blow steering wheel PM if you have a complete one for sell.
