Charles you should be on the right track with a factory restoration, as much as that is possible.
Restoration stuff/ radiator clamps I found this one yesterday & noticed they had a plethora of hose clamps; they'd know what you need.
Call the Filling Station, Jim Carter, Classic Parts, the other ones- most of them
should be prepared to answer your questions on what came on your truck, originally.
I have found this forum is collectively better at knowing a lot of it, because we collectively own most all models and have identified the changes over the years. Sorting through all that "mis-information" is kinda what we do.
