Thanks to everyone!

I have spent hours leveling, measuring, checking, and re-checking. I finally got everything squared off and the frame is VERY close to straight and level. I spoke with a tech at No Limit Engineering and asked him my questions. He thought everything will work out fine. I am having a hard time with what kind of tolerances are expected.

I was also able to finally find the true axle centerline and got it transfered to the frame.

I keeping looking it over, my IFS kit will be ordered at the end of this week. Looks I am ready to take off the leaf springs / front axle and move on.
