Here's an informative article on installing Classic Fabrication's floor pans into a "51 Buick Super as well: http://www.webrodder.com/article.php?AID=213&SID=3 It will show the quality of their panels, and any pitfalls you could run into installing them. In my opinion, Classic Fabrication produces very high-quality panels, and with a little patience very nice results can be achieved.
