32 frame builders... i might have an issue

I just wasted my first work day on the frame...Today i started laying my ASC '32 rails using Wescott's diagram for '28-29 bodies. Here is my confusion, i laid out the measurements down the rails but none corresponded to the holes punched in top of the rails "as in Wescott's diagram". I used a square and tape measure so i know i didnt measure incorrectly. Are the holes stamped out wrong or what? Any imput would be helpful, thanks!

 

I'm pretty sure the Westcott plans are based on a original frame,,I wouldn't worry too much about the holes,,your not restoring so drilling new holes should correct any alignment problems. HRP
