You're missing the diameter and knurl length for a Chrysler K-H fixed caliper rotor and hub assembly.
Even for the rear drums, I'm not aware of any off the shelf long studs that can be just pressed in to replace the Chrysler 7/16 studs. I had a set ground and reknurled but there are other ways to skin that cat.
For the k-h hubs, your options are
a) Find the original 4.5" bolt circle versions (very very rare) and even those I'm not sure came with long studs.
b) Order from Australia for Aussie Valiants. long wheel studs for factory discs
c) Have something made.
The place listed above is one place that will machine and heat treat them.
Another place does similar Wheel Studs - Made in America by Wilson-Garner Company but rolls the threads.
There may be other shops willing to do this work too, but these are the ones I know about.
