70 duster: updating, and a no-dough pro-touring makeover

I had a similar problem with my upper control arms. I bought some cheap new UCA's on ebay for 100 bucks with all the bushings and had somebody install them. They had to grind the lip, too and when I changed to the wider 5.5" wheels I had to grind some more. I wish I had put new bushings on my original control arms. I still have them and may swap them out one day with new bushings.
