I used a jack (quick and easy) for the front axle while the rear I replaced the degraded bushings at the same time. The bushings will have a pretty good grip on the bar so it can be stiff but it will move. A good size dead blow mallet will probably make quick work of positioning the bar.
Regarding the angles and such, you can have the links replaced or lenghtened that will set the bar angle back to where it is used the original holes. Myself, I'm at 40K miles post change with original links and no problems.
