Best factory restoration books/reference

So while I'm enjoying my Barracuda, I'm thinking about what direction I want to go with it.
And I guess what I mean by that is I am a big believer in build what you enjoy (otherwise what's the point? )
I have a big block 4 speed Challenger that I have no reservations about what changes or upgrades I make to any aspect of the car.
But I feel like with the Barracuda, even though I realize there is nothing numbers/investment wise of significant value, I want to keep or improve the cars originality.

A little back story is that the car is 1967 273 auto trans Barracuda.
I've read the casting numbers on the block, is a late 66 block (I need to get the power steering pump out of the way to confirm machine date ), the fender tag decodes as being ordered January 6 ( which is cool as my B-day is only a couple of days later )
The dash, interior and all of the colors appear to be correct.
Heck the car still has the original Certi-Card.
So I earlier this year rebuilt the BBD carb and thought maybe I should and kind of want to continue getting the car correct.
While I have many of the correct large items in/with my car, things like hoses, the battery and cables are not correct. Someone even went and painted the engine orange, so I have a few things to work out.

So my long story has brought us here, what would you recommend for reference information?
Thanks for your input :)
