How much trouble will it be to rebuild the front end?!

I only trust NAPA parts for front suspension and brakes. So my price was $163.99 for the idler arm for my 67. The part might have been made at the same place as Advance, Autozone, internet Jap/Mex suppliers etc.... but I only feel comfortable about NAPA. I feel pretty stupid now but what can I say I didn't know about the trick RedFish spoke about.
