Paul, sorry I took so long, loved the e-mail of your red nose..lol.
If you "patina" the hood just the way it is, red, then you will have a survior look that is credible. Then it will just look like the person needed a hood replaced early on in owning the truck, say it was stolen, and he got one from a wrecked truck and it aged right along with the blue body.
Not everybody saw the need to make work truck panels match back in the day because trucks got pretty beat up and abused by their owners on a daily basis.
