Steering wiggles

I just finalized my conversion to BBP front discs and rear end parts and I am having an issue with the manual steering. Going straight no issues but once I turn for lets say the first inch of steering wheel travel there is a wobble in the steering. Once I get past that initial inch or so the wobble goes away. According to the alignment shop we are good there. It has tubular upper a-arms instead of stock. Other than that it is stock '73 stuff on a 67 cuda. Lower bushings seem ok but will be replaced next winter for upgraded rubber ones. Anyone seen this before?
