A/C wires not an option on new wiper harnesses for 68 barracuda - where to find?

I called MH directly before posting this listing. The MH rep said that for the Mopar harnesses, MH only assembles the pieces for Year One who has the tooling and rights to the Mopar parts. MH rep said they get all the pieces from Year One to then make up the Mopar harnesses. MH said they don’t sell direct and they couldn’t provide the pieces so I could add the a/c leads to the one 68 Barracuda wiper harness they do sell.
I will call MH again and specifically ask if they can do a custom one but my sense was from my earlier conversation is that the MH rep didn’t offer when I was trying to find a solution on the phone with them.
So, seems like there are a couple options-
-MH makes a custom harness if they can.
-I buy the MH harness without the a/c wires and buy another one from them for a different car and cannibalize it to use parts to add the a/c wires.
-I contact Evans and see if they have one or can make one.
-I scavenge parts off a old one to build my own. ( I have the original harness with a/c wires but missing one of the ends that goes to the a/c )
