C10 Trailer Hitch help needed

[kiteman]

Looking for some help in identifying a C10 trailer hitch connection.  I've listed a trailer hitch for sale that came off my '04 C10.  (http://www.zggtr.org/index.php?topic=9354.0)  Since it came with my bike and i never used it, i'm a bit baffled by the rear connector and what interface is needed to connect this to a trailer.  This seems like a commercial manufactured unit that is very well made, yet i haven't been able to find anything on the web that even remotely looks like this connector. 

Is anyone familiar with this hitch that can help shed some light on what connector is required and how to go about getting one?  Thanks......

I can not say for certain and I can not find anything online but that sure looks like a mount plate for a military style (pintle) hitch. You know the circular one that locks closed as if to form a chain link. Logically I could see this used for a motorcycle as you could then have the eye (solid circle) on the trailer able to pivot. I am not having much luck finding one but will start looking a bit harder.

Looks like a Unigo hitch. ( Single wheel trailer. )

I have to agree with Works - that looks like a close mate / match for what you have pictured

Thank you!  That's definitely the right match.  I even found the C10 hitch hiding on their website under the Suzuki section.
