Where can I find the 12+16 SSD logic board connector?

I’m helping a friend revive a MBP Pro 2014 from an accidental spill after sternly admonishing him for being a menace to his MacBook Pro while drinking his juice. Luckily, his data is safe, but several pins on the nameless, proprietary 12+16 SSD connector on the logic board are charred for life. I’m planning on replacing it with a new connector.

I’ve read the connector referred to as "gumstick" on the board schematics. I have conducted extensive searches, but I can't find it listed anywhere as a replacement part. I find it surprising given how easy it is to find other connectors and it's vulnerable location for liquid damage. I did find it on a few PCIe adapters, but the profile doesn't provide enough clearance for the bottom cover.

Any ideas where I should look?
