70 Duster Front End Rebuild Help

Sometimes I think we are all dreaming of suspension parts that will last forever. That's probably due to the labor involved in replacing some of these parts. I remember doing front end work in the 80s. Every daily driver over 7 years old needed some things replaced. The 5 year olds would need 1 of these and/or 2 of these. I can still hear the customers complain, "Every time I get alignment I need to replace something", as if we were running a scam. Sometimes I would walk them to their car to show them, "This and that has been replaced. Today you're needing the other this and that." If there was a benefit, Their money and my labor was spread over time.
Bottom line... Nothing lasts forever. Buy the best parts you can afford today and plan to live long enough to need some of those same parts again someday.
