In 1970, would the consecutive unit been used only one time for all the Mustangs built?
For instance, could a Dearborn, Metuchen and San Jose Mustang all have the same consecutive unit number in the vin being that the vin could be distinguished by the plant of manufacture even if the engine and model were the same. For instance, OF05Q123456, OT05Q123456, OR05Q123456.

The consecutive unit number was only unique at a given assembly plant. The same number could have been used on a car assembled at Dearborn, Metuchen, or San Jose/Milpitas.

This would also be why the plant was mentioned in the engine stamp partial vin.

Certain portions of the VIN are use to identify any car. The first character identifies the year (your letter O is actually a 0, zero - a number); the second is a letter for the assembly plant (we are familiar with F, R and T for Mustangs - go to wikipedia and look up Ford Assembly Plants); the next two identify body style which includes all Ford, Lincoln, Mercury, and others; the next is a letter for engine code. The sequential number starts with a 1, as in 100,001. It may also start with any other number, for any particular year, for any particular vehicle line, for what ever Ford wanted to do. For Mustangs in the 1965 model year, Dearborn started with 250,001, San Jose started with 125,001. Ford made up it's own rules as it built cars. The only creteria was the VIN had to conform to federal standards and be unique.
Engine ID was plant and sequential as Tim stated.
