Welcome and thank you for allowing me to assist you! I found the coupler at Rock Auto. go to http://www.rockauto.com/
It is made by Dorman, and the part number is XXXXX
I hope this helps, and let me know if you need further assistance with this.
Jeff, I have looked around this evening for your coupler and I keep finding that same coupler that we found on Rock Auto. I am thinking that this kit is used to rebuild your coupler and that is why it may look different. What do you think?
Ok Jeff, let me know how it goes, and thank you for the positive rating and bonus!
