Actually it has been done. Don't remember the company, but I'd say it was around a year ago when I saw them. The guy was selling them for around $350? or so.
I'm a huge fan of skirts since I had them on my Insight....as well as a few of the 50's and 60's cars I've had.
I'll try to remember the company, they have been done ....AND it was on a 451. I think the company was in California.
