A little detail often missed/skipped when doing a restoration is the rad hoses. The originals had a somewhat faded 1/8 wide white stripe running the length of the hose with "breaks" for the numbers, and breaks at each end. I found an nos hose, and duplicated the stipe on the two rad repro hoses for my 68 Chevelle. I've noticed the diehard Vette guys use a blue stripe for their application.
