You may be able to reduce the angle by raising the tail shaft of the engine/trans. See if you have room for shims. If you can get it below five I would think it should be OK. When you think about it, recommended for a leaf suspension is 5 to 7, and the rear axle is not angled from being under load on deceleration or real light loads. So it doesn't sound as critical at 5 degrees as we think.

The lower the bars the less it will lift the chassis Usually Go try it, also try measuring(the pinion angle) the car at rest and at full front end extension hieght with the front wheels off the ground also, see how much it changes and go from there, watch the rear U joint angle and clearances

i thought the pinion pointing downward would cause the front to lift? or have i got this a about face? at the present set up we lifted the front & pretty much dropped it straight back down. i was hoping to carry them a little further & was told lower the bars will do this. i cant test at present as the engine & trans are out while the car is getting a facelift but do adjustments at the rear whilst this is happening.
Actually the higher the front point the harder the hit... lower is softer... if it was out farther it would tend to lift the front more(closer to the CG of the car)... from what your saying it pops it up then drops, its hitting the tire too hard... also the lower will tend to push more
