I've actually not seen a Chrysler Wizard, but have seen plenty of Chrysler Sea Kings and straight Chryslers. In mt opinion, they never won any points for their stylings. Unless you are trying to be true to the original style (which I can appreciate) it might be a good candidate for a custom paint job. If you have a boat with a special paint scheme, perhaps do something that will compliment it.
I searched high and low for a Chrysler Wizard picture, but no luck. Whatever you do, have fun with it!!
