68 K10 Suspension

[68C20]

I have installed a 6 inch suspension lift with new springs at all four corners. The issue I am running into is that my rear axle appears to sitting about four inches forward from its original position. This is causing the wheel to sit forward in the wheel well and the driveshaft is too long to be reinstalled. I have also run into an issue with the steering box to steering arm on knuckle. Nobody that I have talked to makes any kind of raised steering arm or dropped pittman arm. Has anybody run into this issue and how did you correct it?
