That is a great find and a great story.
To clarify some points about the original build.

This has to be the first case I have ever seen of chromed front and rear bumpers being replaced prior to first sale. The factory painted front bumper would have been white in this case.

The rear bumper is typical of a dealer sourced and installed example. Many, like this, are positioned lower than the factory option rear step bumper.

Radios were an option and this truck was assembled without one. While the term "radio delete" is commonly used it isn't actually correct for 67-72 trucks. Only in the case of a base build, line item not being installed for a credit is it then truely a "delete" option. Heaters, bumpers, spare tires and hub caps come to mind here. Though on later vehicles, when radios were standard, they could be deleted for a credit by law. Same goes for the "radio opening cover plate". :-)

On this particular radio it appears to be later than a unit the dealer would have installed new in 72. In fact with the box speakers it looks like a late 70s typical "boxed set".

Finally since this is your "pattern truck" the arm rests to be correct are white "as built".

Thanks again for sharing these pictures of your new truck.
