wiring

[57chevyman]

hey y'all
i know this has been covered, but can you point me in the right direction for complete wiring kits.

my truck has real old wires and im thinking to rewire the truck with a new fuse box and all that stuff. for peace of mind that i know the wiring is good.

i heard of "painless" wiring kits? is that the good stuff?

i need a pretty basic kit. no computer or fuel injection or sensors or ABS..

i have a SBC engine. no AC, but i may do it one day.
