M26 "wheel lip mouldings" were STANDARD on the '70 'Cuda (HEMI included).

at the begining of the model year:
HEMI'Cudas were Hamtramck built with wheel lip mouldings & shipped offsite to have the fenders rolled & wheel lip mouldings "hacked" to fit

at some point during the model year:
Factory installed rolled "HEMI FENDER" became STANDARD on HEMI'Cudas - some with and some without wheel lip mouldings both on the car and broadcast sheet

by the end of the model year:
HEMI'Cudas had factory rolled "HEMI FENDER" with NO wheel lip mouldings

FWIW: an original idea for the AAR'Cudas (& T/As) was to have G60-15 Polyglas GT tires on all 4 corners - this would have made it necessary for the same rolled fenders (& NO wheel lip mouldings) to be used - this didn't happen but it is the reason you will see factory original rolled fenders on some AARs.
