PullRite hitch - repaired damaged component

I had to repair the lock lever assembly on my PullRite. Pictures of the damage are shown below. This is what I call the "trigger" which the pin contacts and trips the spring loaded lock to hook and secure the pin. I assume it was damaged when we tried to re-hitch with the king pin too high due to approaching on an upward slope, causing the lock lever trigger portion to contact the bigger diameter section at the bottom of the pin rather than the smaller diameter section that the lock is intended to hook around. I noticed the pin then started to catch a little as I drove out after pulling the lever and unhitching at subsequent stops. I inspected it and noted the damage.
I called PullRite to see if it was covered by warranty. They did not have my warranty registration on file, but offered to send me a replacement kit free of charge after I described the damage. Kudos to PullRite!
I am certainly no master mechanic, but I was able to complete the repair myself. It requires taking the plate assembly off the hitch, undoing two springs, removing a push nut then changing out the part with new washers & push nut included in the kit.
We have resolved to watch the pin placement more carefully, especially on site with sloped access. We normally hitch with the king pin low, causing it to "ride up" on the plate assembly. Apparently we did not do it correctly when we damaged the part.
