I am getting ready to put my pinto ifs under my '48, I preped the frame today. As far as I know, you would level the frame front and rear. Center the spindle in the fender well(Pre-Marked), making sure that the center of the spindle is the same distance up or down from the top of the frame on both sides. Then cross measure from the inside rear corners where the new ifs meets the frame and the rear inside corners of the frame.

If I am doing this wrong or am missing an important step some help from you all would be most appreciated.

I am really excited to get on with this part of the construction and get the chasis rolling again....Thanks all.
