Since all the bushings are poly, can I assume you've had a recent alignment? If so, you may want to take an hour and map the rear wheels against the front end and verify the rear toe and the thrust angle.
Did that and all is good. I thought maybe they aligned it toe-out but it is toe-in. Rear also has just a little toe-in. Drives straight down the road but when you first turn the wheel, it kind of takes off and I am thinking maybe more air pressure would help. Also I have Yokohama S-Drive 225/50 directional tires that may cause a little darting.

Wouldn't surprise me at all, when you consider that the suspension geometry was designed in 1960-61 around 6.70-15 bias-ply tires on 5-1/2" rims.

I think you would be happier if you disconnected your rear sway bar or removed it. At least try it! Next step would be to check your corner weights.

That's kind of what I was thinking since all else seems to be good. I think I might try a little more air in the fronts but I just need to get use to it.
