Who Makes The Best Original Wiring Harnesses?

[67camarors]

I have a 72 gmc sierra that is all original. My original wiring harness is perfect, but the a/c fuse keeps blowing out and the fan only works when you have the fuse in one certain way, so I know it is in the fuse block.
Anyways, I want to buy a new underdash wiring harness with fuse block. I want one that is just like the originals and require no splicing. Does anyone know which company I should go to? I hear American Autowire and Lectric Limited are good. thanks
