One piece floor section. .039" Drawing Quality Cold Roll Steel. I am considering offering these floors for purchase with the following terms, 1) the floor would be pick up only in central southern Missouri, 2) with the floor I would include a simple fixture to aid in an installation for the "do it yourself," 3) I would set a date for a two day seminar and show the purchaser how I go about installation, 4) the condition of the car surrounding the floor panel would have to meet certain conditions as yet to be specified, 5) a customer donor car would be required to be brought to my shop and prepared prior to the seminar a list of what would have to be removed will be provided. I would welcome a restoration/body shop to attend as well. I would provide coffee and pastries both mornings and a pizza or subway lunch both days. There is a Super 8 12 miles north in Ava, Missouri. Each of these cars is 60 plus years old and you never know what you will find. So as far as the instructional seminar goes we will have two days to install the floor. More than likely the return around the bottom that the floor panel sits on will need repair so that is a given. However there will not be enough time to address issues beyond that. That needs to be understood. I will update as I can.
