When I wanted to rewire my stock 49 I checked almost everyone's product. Could not find one that was basic. They all seemed to have features like alternator, power window, steering column ignition and so on.
I took a look at the wiring schematic and realized it was actually quite simple. I bought wire, terminals and rewired my truck myself. Simply did one wire at a time. The most difficult part was wiring the dash because of access.
I don't know if a 59 would be more complex than my 49 but I think its worth a try.
