Hello,

I have a 69 GMC 6500 2 Ton Flatbed. The wiring is a mess due to years of hacks and workarounds. The only real difference between the cab of this truck and a 69 light duty is the 5 speed Eaton split shift. All other dash and electrical parts seem to be the same.

Anyone have experience buying a wiring harness from Painless or American Classic? They don't have the one I need for my exact truck, but wondering if anyone has gotten one and only need to do a few modifications to make it work on a similar truck like a C40 or C60?

Thank You...
