Main wiring harness for 70 Dart Swinger

I am in desperate need of a main wiring harness that is located on the firewall below the windshield wiper motor. This harness block attaches to the firewall and wires go to everything under the hood and inside. I just need the wiring block but will take the wires with the connectors, the wires can be cut if you have to but prefer as much intact as possible. I contacted Year One and they are back ordered till September or later.

Please help, car is down until I find this block as a few wires shorted out and burnt mine up. From reading about the amp gauge on this site I now know why.

I will pay for express shipping so please let me know if anyone or anywhere to get this wiring block.

Thanking you in advance.
