Example: if the stock wheelbase was 100" then anything between 90" and 110" would be within the 10% rule or if stock width is 60" then anything between 54" and 66" would be within the 10% rule. Can you please clarify this rule?

I am interested in how the rule functions as well. Certain elements of my truck such as wheelbase and cab dimensions are roughly within 10%. My bed length is not though. That said, all major body panels are from a '47 Chevy truck and my truck is a '47 Chevy truck both in form and legal registration. I guess my first question is what dimensions matter?
