Hey Nicolette,
I didn't get the picture but the Demco Channel Tongue Trailer Coupler # DM16080-81 is 16" in overall length and has a 10-1/4" channel length. I measured the mounting holes from the coupler end back and drew up a little diagram as well so you can see if this matches up to your current bolt pattern.
If you have any other questions about the # DM16080-81 or still need help picking out the correct replacement just let me know below in the comments and I'd be happy to help.
