CA WTB Discontinued electrical connector

[PbFut]

I am in need of one connector Packard 56 type. It is a 4 pin connector on the interior main harness that connects at the firewall to the intermediate 4wire ribbon cable that runs to rear of truck for rear lights. The connector has 4 pins and connects to a round grommet plug. 2 vertical and 2 horizontal Pins and has a rubber gasket to seal the opening on the firewall. I need the Female pin side on the interior cab harness.

I spoke with a very knowledgeable rep at M&H Electrical. They make the harnesses. Everyone else just puts their name on M&H's product it seems. After some searching the M&H rep found the part. They have it in the "lifetime inventory" Meaning they bought the last run in 2005. When the part is used up in their inventory for their harnesses, that is the end and an alternative will be used. No options and they will not sell an individual part.
It appears it ran the full run 67 to 72 and maybe later. Possibly 74

If anyone has an old harness that is damage and wants to turn loose with this connector, I would be interested. It is hidden away and so I could cobble up a substitute, but I would rather have a correct connector if possible.
