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

^^^Later on^^^ If you decide you are an auto cross/ road race son-of-a-gun, THEN you can ditch the stock suspension and put something fancier in there BUT THE STOCK FRONT ENDS can be made to handle well
The coil-over suspensions have not proven to give any advantage except to the vendor that sells them. They get your money, you get a system that looks pretty but performs no better.
You can go fast with a stock based system.
