PowerSteering

Yup, 65 Dartman is on the right track: you are shopping in the wrong places. RockAuto sent you what, a piece of junk ruined by Cardone? And some rando on Amazon, yeah, that's not gonna work. Get with RedHead steering (there in WA state), Steer & Gear, and/or Firm Feel to get the right parts in quality worth your time and effort.
