Repro dash wiring harness

I'm getting ready to pull the dash on my 66 Barracuda and I wanted to replace the wiring harness or harnesses (just don't trust the 40+ year old insulation) while it is out. I will be overhauling the heater box and fresh air vents as well during this endeavor.

My question is can anyone recommend a good source for replacement wiring harnesses? I'm looking for ones that have the OE correct connectors and will drop in without modification. Has anyone bought any in the past few years?
