Go with the resistor values from the output transistors on the Frank schematic you have, or from that power amp section you put into the other amp.
You want the output trnasistors to idle at close to the voltage and temperature of these other amps.
Just remember to switch those wires, here`s the reason why.
Going from PNP TO NPN types, or the other way reverses the Phase of the output stage. In a feedback type amp like the Kustom this will make the amp howl like mad when you turn it on, swapping the V+ and V- wires reverses the Phase once again so you are back to where you started.
