70-76 A-body instrument cluster pigtail

If anyone has a dash harness they are cutting up, I am in need of the main instrument cluster connector and 6-8" of the the wiring. This is the round connector that plugs into the PCB on the back side of the cluster. I see a couple on eBay from 70's/80's trucks for 10ish dollars but the wiring isn't long enough for what I want to do.

I am putting aftermarket gauges in my car and I would like to make an adapter harness for easy change back to factory gauges in the future.

These are two I found on eBay. Either of these styles would work. I just need more wire length. Let me know what you've got!
