1970-71 dodge dart differences.

Here are the most noteable differences that i know of:
Grilles are the same, just different colors.
Emblem placement on upper quarter panels on a '70, and on front fenders on a '71.
Gas tank and filler tube.
Steering wheel.
Rallye gauge cluster is a '70 only thing.
Rear bumper and tail lights
''Dodge'' emblem on the hood is in the center on a '70 and is in script not block letters, emblem on trunk lid is the same script as front but has different attaching pins.
Center cap color on rallye wheels, light argent on '70 and dark gray on '71.
Hood and scoops, can modify the '71 hood to fit the '70 scoops.
Slots in the bumpers on late production '71s.
Obviously the 340 engine wasn't available on a '71 Swinger. Some Canadian sold cars were available with them from the factory, but they are very rare.
