I am needing to replace my idler arm, pitman arm, and inner tie rod ends on my crew cab lb7. I am going to install the cognito braces when I replace all of these parts. I just wondered if I should go with OEM parts or MOOG brand parts? Looks like roughly $250 at gmpartsdirect for OEM parts shipped. It is about the same for MOOG brand parts at O"Reilly Auto Parts. Also I wondered if I would likely need the idler arm frame bracket pivot assembly? It seems to be packaged with the idler arm if you buy the OEM brand but is a separate piece if you go with the MOOG brand and seems to be a very uncommon special order only part.
