There were two styles of AD radios that were basically identical for Chev and GMC. The 1947 to 1950 had a back with a slanting parting line on the sides. The 1951 to 53 radio had a back with a straight vertical seam. The side contour of the two radios were different as you have noted. Both radios will fit all of the AD years.
