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

When I called MH(spoke to Darryl)approx 2 years ago in regards to our 67 fastback in the middle of rewiring car complete from dash to tail lights, there was a couple reasons.
The cargo light bulb holders, our originals were brittle. They sold me new ones no problem.
Rear harness for cargo light(can't remember whether pass or driver) is not available from Year None and Darryl specifically said they can make it for me no problem, BUT a 6 month wait lol.
Sorry you're having issues, from everything I've read Evans sounds like an awesome Ma n Pa operation.
