Unhappy Re: is this normal?

These are measurements i pulled with the frame leveled out on stands, no cab or Sheet metal
on the truck. The front is sitting on the suspension(axle on jackstands. ) I have the motor, transmission and case installed for weight. I'm installing a sky manufacturing 4.5 perch drop( everything just tacked in place, and 6" lift springs. I plan to run 40's. I need mock up the front so i can measure for some rear alcan sprngs, and i already have a 4" flip four the test of the lift.

Do you think when add the cab, sheet metal fenders hood the leaf springs will flatten out and castor will get better in 3 to 7 range? I can move the spring hanger and front shackle brackets around but right now they have my axle centered for the wheel well. The shackle angle looks good too, about 10 degrees kicked back perhaps even a little bit more with added weight.

With 40's Do i still want to see 3 to 7 degrees, I've heard less with big meats. I guess it looks like I'll need shims right???
