Wiring kit recomendations for a 61 short bed please

[el_guapo]

Goodmorning from Colorado,
I have a 1961 chevy short bed that I am trying to find a wiring kit for.
This will be my first time re-wiring a vehicle (the simpler the better), I am having a tough time finding a kit specific to this year.

My truck runs a 283 with a powerglide if this helps.

I have heard good things about "painless" kits, however the kits they have (all I find) are for 63-66 trucks.
