As posted above, if you have a title with the engine code AND the vehicle code (or a sales slip with BOTH of those codes), you could demonstrate that you have a "numbers matching" truck. However, most titles and all registrations have only one of these codes on them.
The only other exactly matching numbers might be the engine code for a Hydra-Matic equipped truck - that engine code is stamped onto a plate that is attached to the Hydra-Matic transmission. But, the vehicle serial number does not designate that the truck has the Hydra-Matic option.
Otherwise, before 1957 your "matching numbers" would be having the same years on the engine serial number year and the vehicle serial number year; and, one of those codes on the title and/or registration.
From 1957 onwards, you could have a numbers logically-matching truck if your vehicle serial number year-code (and series code) is the same as the engine casting-date year-code (and series code). This is tricky at the end of a calendar year, when the engine was cast at the end of the last year and the truck assembled early in the next year.
This is confusing and is fraught with inconsistencies.
