Hi there. Do you still have these, and if so, what are the exact sizes of yours? I have a 1938 DeSoto that yours look like they would fit - my opening is about 15-1/4" tall and 29-1/4" wide at the bottom (31" wide slightly further down where it would curve out a little). Oddly I keep seeing reproductions for sale that say they are for 1938 Chrysler, Dodge, Desoto etc but they are tear shape. Mine is definitely a 1938 DeSoto and the opening is definitely not tear shape!
