Diffrence 71 and 72 charger

[twin 72's]

Just wondering if any one could tell me the difference between the 71 and 72 other than the engine options, rallye package tail lights and side markers. 

[Nacho-RT74]

-upper panels design, wider insert on 72 to standart interior, and new brougham package option

-buckets seats foam and all covers

-seatbelts using two female buckles on 71, and one on 72. Set up is diff due that.

-seatbelts warning system. Time delay flasher controled on 71, and linked to seat and seatbelt sensors on 72, controled by a relay

-6 bows headliner on 71, 4 bows headliner on 72, however some are mixed because the crossover

-hood grill, one complete side to side on 71 and with a blank space in the middle about 2" on 72, however some are mixed because the crossover

-hideaways, more vertical fins on 72 and not anymore DODGE badge on grill

-of course, grilles are diff

-wiper switch

-jack slots on bumpers on 72, plain on 71, so diff jack

some other diff are related with mid year 71 production, like no console ashtray on first half 71 and diff buckets backs...
