Hi all, Does anyone know the differences between the swivel seats of 1959 versus 1960? I want to put original looking seats into my 1960 New Yorker and there's a set from a 1959 on eBay right now I'm considering. One of the strange things is that the 1959 appears to be out of a 4-door model. Has anyone ever seen swivel seats in a 4-door before? Item #2453708670. Thanks, Gary Runkel Canton, MI
