IIRC Frank's kit had all the necessary hardware and I was very pleased with it. As to what was on my car originally, my project got stalled out over too many years, I'd started disassembling in '99, and didn't document everything as well as I should have. I do have the remains of one of the valence brackets, which was corroded and replaced, and it had one of the long screws installed in it.
Thanks for the picture of Dave's backing plates. They do look natural cast iron. The resto shop painted mine with something more silver, not cast iron paint. rant
They also didn't put any markings or paint daubs on my axle housing, and painted the pumpkin with a paint I'd call battleship gray, when I wanted it natural unpainted iron, so I really need to take the rear axle off and redo everything. bawling
