First step to restoring my 1974 Duster; Front End rebuild (coilovers needed?)

BTW 73 should be the same as 74.

There may be a couple of things slightly different, but for the most part- same.

IIRC The biggest differences will be drum brake vs disk brake stuff.
If you are saying the service manual, the wiring is quite different each year in all years 72--76

Mechanics is likely pretty unchanged
