I had taken off of my 8N what I believe to be my swinging drawbar clevis assembly in order to clean it and the surrounding area before painting. When I put it back on I noticed the spring in the hole for the pin did not seem correct and I began to investigate. In the book the assembly is quite different. Mine has the point of attachment in the very back rather than in the middle. Is this just a different style? I do not have anything other than the bracket itself. I would like to make it complete. Where do I go to get parts or do I replace it with what is in the book? I can attach a picture (I think) later if needed.
