Galen Govier's "white books" contain production figures based on Chrysler Corp.'s "OPTION & ACCESSORY REPORTS" that represent the majority of US shipped units (as of a certain date in time during August 1970)

for example: the '70 'cuda hardtop (BS23) numbers are based on 88.5% of total production, this leaves 2,170 '70 'cuda hardtops uncounted in this report

the only pertinent combined OPTIONS covered by this report: BODY (BS23) / ENGINE / TRANSMISSION / AXLE PACKAGE (if equipped)
