73 dart front end to 68

sorry,

want to change a 73 dart front end to 68,

but, I am also curious whatt the front end and interior of the 71 valliant 4 door will fit because they are in pretty good shape.
What it will fit and what is correct are 2 different things with these a-bodies.

('71 Valiant 4 door front clip and interior)
Direct fit and correct: (other than some trim and emblem holes)
'70 and '71 Duster, Scamp, Valiant.
Hood and front bumper with brackets, as well as front valence will work on a '69 Valiant and would be correct.
Grille is '71 and '72 only.
Front valence and bumper brackets along with hood latch and brackets etc. '70 - '72 Duster, Valiant, and Scamp.
The entire dash, wiring, gauges, controls, heater box etc. with steering column and wheel, and pedals are the same for '70 and '71 Duster , Scamp, Valiant.

The kick panels fit many years.
Dash pad fits many years.

Will fit but not be correct: (other than what is stated above)
'67 -'69 Valiant, '72 - '76 Duster, Valiant, and Scamp. (entire front sheet metal clip, everything that unbolts)
All of the dash components and pedals.
Steering column and wheel. (it is the same for many years though '70 - '76)

This is not a 100% complete and thorough list, as there can be some variances with small items and details that change a little throughout the production cycle.
This should get you going in the right direction though............
