Axle swap/ pinion angle

[DBear]

Hey guys...just got done swapping a gm14 bolt into my 71 K10 suburban. For suspension set-up I am using stock rear springs out of a mid 70's truck with an zero rate attached to the leaf pack. I am also using a 3 inch lift block from Rough Country to get a 4 inch lift total.

Here is my issue.....with it all bolted in, the pinion yoke is sitting about an -3 degrees angle, meaning the pinion yoke is pointing toward the ground 3 degrees. Also, the spring pads on the axle tubes are doing the same......and....the u-bolts are slanting forward (toward the front of vehicle) as well. This is turning into a small nightmare. Any suggestions?? They would be greatly appreciated.
