Otto you asked,

Does the steering wheel return to center normally when driving on smooth roads? Not really. I have to steer it back.
Will it track straight if you let go of the wheel? Yes, on a smooth straight road.
Is it easy to steer? It steers easily enough once you get moving

They are not the original rims. I'll have to check since I put them on years ago but I believe they were 8" which may be contributing to my problem?
Also when setting toe in toe out at what point is that being measured? Across the front edge of the tires? Geometrically the distance you make the measurement in relation away from the centerline of the spindle all comes into play since we are forming a triangle.
