The initial portion of the IFS conversion of course requires the removal of the International’s original suspension, but beforehand, Dan located the front axle centerline and scribed the top of the framerails so the new crossmember would be located correctly and the front wheels would be correctly centered in the front wheel openings upon completion. Once the frame is scribed and devoid of the old components it’s time to make sure the frame is both level and square. In the case of this ’50 International, there are some original frame rivets that can be used to determine this. At the forward end, the two rivets holding the front crossmember to the side framerails are good datum points. On the aft end, the two rivets holding the crossmember (over the rear axle) are the other good datum points. The diagonal distance between the points was measured to confirm the frame was square. If the measurements differed by more than 1⁄16-inch, necessary action should be taken to improve the square. A come-along from corner to corner could be used to achieve this.
