Good info on the shims. I don't have power steering but have quite extensive mod's to the OEM steering assembly to shoe horn an SBC in. I retained the existing shims that was on it and for the most part the steering returns to straight except when I go full turn to the stop, then I have to manually start turning the steering wheel until it hits a sweet spot and it returns on it's own.
I'll add 6 degree shims to my shopping list.
