Can’t get 1968 BB to crank over

Sounds like the battery may be dead?
Have you checked the simple things, that’s what’s easy to overlook.
The wiring is the same as it’s always been. All ignition wires traced from start to finish
Battery is one week old 12.5 volts
New relay on driver fenderwell
New ignition switch
I even used my old one that wasn’t even broken
The wire terminal positions/configuration in the 1968 Plymouth manual does not match up with the actual ignition switch yerminals
Book says bottom terminal black wire is for accessories the actual ignition switch days ignition 2
This is what I’m dealing with and one or two others
