Sync cord for old Sunpak GX8R ring flash

[usayit]

So I acquired an old Sunpak GX8r ring flash that has everything but the sync cord. Looking at it, I made the assumption that its a regular-run-of-the-mill PC sync cord... great I have a bunch. It was a wrong assumption. It looks like a normal PC sync connector but it is a variant that is further recessed and has some sort of locking mechanism. None of my cords have a long enough tip to make contact. Does anyone out there remember this flash and know where I can find a replacement cord? Pictures as follows

This is the pic of the missing cord. The tip to the left is a normal PC sync connector the one to the right is the connector in question.

Here's a pic of the port:

Thanks!
