Hi KbLf,
My knowledge of Auto radios is very limited (12 volt late mid-'50s). I did look up your schematic in the Riders manuals - special custom-built receiver for 1937 Ford V8 with Concealed header bar speaker with ear level reception. it is in volume 8 in the Philco section on page 8-145. I hoped it would provide some voltage readings but alas, no. I would measure the diameter of the wires you have (copper wire, no insulation) and talk to the people at Rhode Island Wiring for their recommendation. They do offer shielded wire in 1, 2 and 3 wire bundles by the foot and I believe that they have the ability to produce custom cloth covered bundle. They also have all the connectors that I believe you might need.
Sorry that I cannot be more specific on the current draw. I did look up the transformer for your radio - Philco part # 32-7720 and the secondary voltage produced is 234 Volts, 40 ma.
Good luck!
Fran
