Auburn fender question

Parts book shows different part numbers for each body style (sedan, 7 passenger sedan, brougham, coupe, phaeton sedan, cabriolet, and speedster)
Front fenders are same, with exception of 7 passenger sedan.

for 31-33 cars are the rear fenders for a cabriolet the same as a coupe or Brougham? or are they all the same?
