Looking for some help with the bracket that holds the dinning table securely while traveling. The Hold Down in my 2007 Excursion is missing and I'm wondering if anyone can come up with a replacement. It seems that the long stud that comes up out of the floor has two different thread sizes, the in floor section being larger than the piece the table clamps down to. I have looked on the Fleetwood web site and the part description is so vague that I'm worried they will send the wrong part. Anybody out there have any ideas as to correct part number or supplier of replacement. Many Thanks in anticipation.
