Some confusion exists regarding style numbers on 1934-35 Fleetwood bodies.
Following the previous Fleetwood system, V-8's would be 56- or 60- styles, V-12's would be 57- or 61- styles, and V-16's would be 58- or 60- styles.
This system was followed in promotional literature, in the 1934 Master Parts List, and in early factory records.
However, since the bodies were identical for all these series, Fleetwood stamped all body plates 57- or 60-.
Master Parts Lists after 1934 used only 57- and 60- style numbers for 1934-35 Fleetwood bodies.
Starting in 1936, V-8 and V-12 style numbers reflected the new 1936 series designations, but V16's retained the 57- system. However, 60- styles were no longer offered.
