I've never seen a floor mount setup on a Contemporary ever...they have always been hanging units. I don't recall seeing it in the manual either. They may exist, but in all my years, I never saw one.

I would think since most of these cars have generic applications, you could simply go to ERA for their setup. When I was building my Contemporary, I used a lot of their ideas ad parts.

edit: I see the setup utilizes the sponson.
